INFINITicon – An English Speaker’s Guide to beatmania IIDX INFINITAS

2020/11/14: UPDATED for INFINITAS spec!

Super shout-outs to K0LDX for creating this guide and to Shinji16 for his work on updating this guide for the latest release!


What is Beatmania IIDX INFINITAS?

Beatmania IIDX INFINITAS is the latest home release of Beatmania IIDX. Designed for Windows PCs and first released back in 2015, it is a subscription-based platform operating off of Konami’s Amusement Game Station (formerly the e-Amusement cloud service) that is continuously updated with new songs and content. In August of 2020, Konami released an extensive update to the client, featuring 120hz support along with many other major quality of life updates. If you’re looking for a way to play newer Beatmania IIDX content at home, can’t get to an arcade with a IIDX machine, or want to start playing the game and support the BEMANI team at the same time, then INFINITAS is for you.

Wait, subscription? How much does it cost? And what do I get?

An INFINITAS subscription costs 1628 yen each month. This can be paid for either with a debit/credit card or PASELI, which is Konami’s digital currency for arcade games.

What you get in return is access to INFINITAS for each month that you pay your subscription. This includes unlimited song play in Standard mode, unlimited access to INFINITAS rival data as well as UI customization. In addition, Konami gives exclusive access to 2 of the songs they add each month to their current subscribers.

Okay, how good does my PC have to be in order to run it?

According to the INFINITAS website, these are the minimum required specs to run INFINITAS:

  • OS: Windows 10 (64 bit)
  • Processor: 2.8GHz (recommended: Intel® Core™ i5 3.2GHz or higher, or AMD A8 at 3.5GHz or higher)
  • Hard Drive: 60GB or more, with additional space allowed for updates
  • RAM: 8GB
  • Graphics Card: 1GB GPU or higher
  • Resolution: 1280×720 or higher (16:9 recommended)
  • Microsoft DirectX® 9.0C or higher
  • Stereo sound card
  • Internet connection (wired connection recommended)

(Be aware the stated minimum requirements are not fully definite. For example, the new client claims to require Windows 10, dropping support for Windows 7 and 8.1, however it has been reported the new client will run on older versions of Windows without issue.)

If you’re unsure if the game will run well, there is a ‘Trial’ version of the INFINITAS client you can run. You can play one of three Beginner charts, and after the result screen of the song you play the program will close. This will let you test your computer and control method of choice and see if the game runs smoothly and your inputs work as desired.

Is there anything else I should know?

Since the game runs off of the e-Amusement cloud, any time that the e-Amusement servers are down for maintenance, both INFINITAS and all related web services for Konami will be unusable. So when does Konami perform server maintenance?

  • Every Day from 5:00 AM JST to 7:00 AM JST
  • Every Third Tuesday of the Month from 2:00 AM JST to 7:00 AM JST

On top of that, some features in the game are locked behind something called INFINITAS Play Tickets; These cost 100 yen or 108 PASELI each and are used to play Class Mode and utilize other features of Standard mode. You don’t need to buy them to play, but they do allow you to do more with the game.

Alright, I’m in. What do I need to do to sign up?

First things first, in order to sign up for INFINITAS, you’ll need either an active (used at least once on a machine connected to Konami’s servers) e-Amusement pass or a virtual e-Amusement pass (more on that later), and a Japanese Konami ID account set up for yourself. You’ll also want to make sure that you have PASELI services turned on for your pass, since not only is this the most likely way you’re going to be paying for your subscription, but if you want to do anything else with INFINITAS that requires PASELI, you will need to have it turned on.

If you don’t have an e-Amusement pass, and don’t live near a Round 1, Dave & Busters or any kind of arcade machine that isn’t officially connected to Konami’s servers, you can create a ‘virtual’ e-Amusement pass on your account in order to use PASELI-linked services such as INFINITAS.

That all said, the first step is to make a Japanese Konami ID and link your physical pass to it, or create a virtual pass on your account. (We’ve got a guide on how to create a Japanese Konami ID [with pictures!] here.)

If you need to create a virtual pass, once you create your Konami ID and have everything set up, scroll to the bottom of your e-Amusement homepage and click on the link highlighted in the picture below. This will take you to where you can create a virtual pass. From there, you just need to input your 4-digit PIN, confirm it, click accept, and you’re good to go.

Once you’ve completed those steps, you’re ready to sign up and download INFINITAS.

Initial Set up

STEP 1: Download the INFINITAS client and install INFINITAS

The INFINITAS client can be downloaded from the INFINITAS website. However, the download link won’t appear unless you are logged in to your Konami ID. Once you are, go to the INFINITAS website and look towards the bottom for the pink INSTALL link. Clicking on this will take you a page where you are confirming downloading the installer. Clicking this will then download the client.

After you download the installer, run it, agree to the terms, and install the game. Once the installation is complete, a web shortcut will be placed on your desktop. Opening this will take you to a webpage where you choose whether you want to launch the full version of the game or the trial version. If you’re not already logged in with your Konami ID, you’ll be first prompted on the website to do so, which will then immediately load into the page that lets you launch the client. Also, on the webpage where you are choosing which version to launch, both the Konami ID and e-Amusement pass currently being used is also displayed:

Once the client has been launched (either the full or trial version), a new program window of the INFINITAS client launcher will appear. At this point, the website can be closed if desired. Be aware the website must be used any time you are looking to launch the client.

STEP 2: Updating INFINITAS to the current version

The base version of the client you download is the bare bones version of INFINITAS. In order for it to run, you’ll need to download updates to make your client current with the release that’s live on the servers. This is done by clicking the little folder and magnifying glass option on the right side of the launcher, or ‘File Check’. If your client is not current, it should prompt you automatically to update to the current before launching the game.

Once you open up the File Check, it’ll pop up with a menu that has two options; Update and Cancel. Since you’re doing a fresh install of INFINITAS, you’ll want the first option. Click Update and let the game download all the updates it needs to make itself current. Depending on the speed of your internet connection, this process could take a while, so be prepared to wait a while during this process. Once it’s complete and everything’s updated, there will be a ‘Close’ button. Click it, the launcher will close and then relaunch itself. Should the program launcher not re-appear, re-open it via the web launcher

Note that this update process will need to be done every time that Konami releases a client update for INFINITAS, which typically is once per month. Also be aware updating the client like this does not download additional songs; “new” songs outside the base library are downloaded “as needed” as soon as you attempt to play them for the first time (such songs remain downloaded for future plays).

STEP 3: Setting up your controller

If you want to play with anything other than a keyboard, you will need a USB based controller, or a means to convert your controller to USB input. That said, this process will be either super easy or will require a little effort depending on what type of controller you’re going to play with:

Konami Official Beatmania IIDX Controllers (Premium, Entry Level, etc.)

These can be hard to find/obtain currently and are unfortunately the only officially supported controller for the game. If you have one, you should be able to just plug it in via USB and use it; The game will auto detect it and adjust itself accordingly without any external support.

DJ Dao Phoenixwan/FP7/FPS/C33/Real Edition/Platinum Edition/etc.

Thanks to firmware updates, these controllers can be used as if they were an INFINITAS Premium Controller and are USB based. If you are using one of these, refer to DJ Dao’s website on how to update the firmware (if needed) and configure your controller to work with INFINITAS.

PS2 Arcade Style Controller/Konami Official Controller

With the help of a PS2 to USB adapter and an external program like Joy2key or Xpadder, you can use these with INFINITAS. However, since the turntables in these controllers are not analog like the DJ Daos or the INFINITAS Premium Controller, navigating menus using your turntable will not be practical since they won’t stop on command or move to your exact speed.

For good, reliable PS2 to USB converters, Brook makes a line of said converters that convert to a wide array of consoles that use USB (PS3, PS4, 360, XB1, etc.) and any of these should work just fine for using a controller on PC. You can find them in a few dedicated places online, such as Paradise Arcade Shop and Amazon.

If you are using a controller that requires Joy2key or Xpadder to run, or are using a USB keyboard to play, this is the default keyboard layout that you’ll want to bind your controller’s buttons to:

1P Key 1 Z
1P Key 2 S
1P Key 3 X
1P Key 4 D
1P Key 5 C
1P Key 6 F
1P Key 7 V
1P Forward Scratch Left Shift
1P Back Scratch Left Control
2P Key 1 B
2P Key 2 H
2P Key 3 N
2P Key 4 J
2P Key 5 M
2P Key 6 K
2P Key 7 ,
2P Forward Scratch Right Shift
2P Back Scratch Right Ctrl
Start/Open Menu Tab
Select/Change Difficulty 1

Regardless of which controller you use (if any), keeping your keyboard nearby is highly recommended, as some game functions can only be performed using the keyboard. These will be detailed later on.

STEP 4: Further setting up Infinitas

Clicking “SETTING” from the launcher will open a settings menu for Infinitas. This settings menu has two tabs, pictured below. The first tab lets you choose which monitor to launch the client in, changing whether WASAPI is exclusive or shared, and whether the framerate is automatic or capped at 60 FPS. The default settings are exclusive WASAPI audio and automatic framerate. For 120 FPS, if it is available, that will be used if the framerate is set to automatic. The second tab will let you re-bind controls before launching the client.

STEP 5: Paying for your subscription

With Konami recently changing their online payment system to allow overseas/international debit cards, the best and easiest method available right now to pay for your subscription is with your own debit card. You’ll want to make sure first that your bank allows international purchases with their debit cards and ask if they will charge any transaction fees if you run your card with an international vendor. Keep in mind also that allowing Konami to charge your card may trigger anti-fraud measures for your card.

If your bank does not allow your debit card to be used for international purchases, and you don’t have a Japanese credit or debit card that Konami will accept for payment, the alternative is using a currency card. BitCash is a currency card that Konami does accept for payment, and these can be purchased digitally from a few places online. OffGamers is the best place I’ve found that sells BitCash cards in the denominations Konami accepts, so I would recommend them should you need to get yourself a BitCash card.

Since INFINITAS costs 1628 yen per month, you’ll want to purchase a 2000 yen BitCash card. OffGamers charge around $20 USD before taxes and fees for said card, and you can use the leftover PASELI however you please. (e-Amuse tickets, arcade services subscription, save it, whatever.)

To add Paseli to your account, once you’re logged in to your account, head over to the Paseli charge station here. Then, scroll down and choose the amount of Paseli you want to add to your account:

Choose the amount that you want to add, and then it’ll bring you to the payment selection page. From there, you can choose either to add via debit card, BitCash or WebMoney which is another service that Konami accepts for payment.

Once you choose your amount and payment method, it will bring you to a confirmation page to confirm both, and then you’ll need to click and accept the Paseli terms of service and then click the grey button in the screen below, which will turn green once you check the box to agree to Konami’s terms.

After that, you’ll then enter in your debit card’s information or your BitCash card’s code to have either Konami charge you or redeem the amount of money stored on your BitCash card. You’ll then get confirmation from Konami that the payment was accepted (and see the Paseli credited to your account) or you’ll get an error page with Konami explaining why things didn’t go through.

Once you have the required PASELI balance in your account, go back to the INFINITAS website and click the big pink button in the middle of the page. This is the ‘subscribe’ button:

On the next page, you’ll see an option for the beatmania IIDX INFINITAS BASIC COURSE subscription. This is the option you want. Click it and it will take you to a second page detailing the terms and rules. The link you want will be below the bold red text. Click it, and it’ll reveal a grey confirmation button take you to a confirmation page.

You’ll be given two different options for payment. Select PASELI as your method of payment and click the big grey ‘Subscribe’ button. Confirm one more time, and then you’re good to go.

Note: Subscriptions end based on the last day of the month, and for renewing subscriptions Konami collects the fees on the 1st of the month, regardless of when you subscribed the previous month. So, if you are looking at subscribing and the month is just about over, you may want to wait until the 1st to subscribe in order to maximize your subscription time.

When you’ve successfully subscribed, you’ll see a green box below the subscription with black kanji on the course offerings page, and the subscribe button on the INFINITAS website will now take you to this page showing that you are subscribed, along with the terms and rules and an option to cancel. This indicates that you’re subscribed for the service and are now ready to launch and play INFINITAS. As for when your next subscription fee is due,

With everything set up and ready to go, open the web launcher, sign in with your Konami ID credentials, and click on the link to launch the full version of the game, which will start INFINITAS!

What if I decide I want to cancel my subscription?

Follow the same steps as described above and click on the orange button on the INFINITAS home page. At the bottom of the page for the INFINITAS Basic Course Subscription, there is an unsubscribe link to cancel your subscription and have Konami stop billing you. If you do cancel, you will be allowed to play INFINITAS until your current subscription time runs out.

Your other option to cancel your subscription is to simply let the PASELI in your account run out, as Konami will automatically cancel your subscription if there is insufficient PASELI to pay for your subscription when the fee comes due and you don’t have a credit card on file to pay for it otherwise.

Regardless of how you cancel, your scores will be saved, and your data will remain on the INFINITAS servers for a time, but Konami does not guarantee that they will stay on the servers forever. So, if you stay unsubscribed for too long, you run the risk of having your play data deleted.

INFINITAS Client Usage and Play

How different is INFINITAS to play?

If you’ve played any version of IIDX from TRICORO or beyond, the game looks and functions similar to that and the current releases that have followed in terms of interface and options. If you haven’t touched IIDX since Lincle and before, it would do you some good to read up on the changes implemented in TRICORO to things like the options menu and hi-speeds at the very least.

What INFINITAS does do differently is a few new options and couple of play mode changes that are unique to the game:


  • KEY ASSIST – Allows chords with 3+ notes to be hit by pressing 2 keys instead. Turning this on also turns on Legacy Note and song Clears count as Assist Clear.
  • ANY KEY – Allows you to hit any note with any key on the keyboard and is meant to be for calibrating timing. Activating this modifier also activates Legacy Note, and songs cleared with this enabled are counted as an Assist Clear.
  • MOVIE DISPLAY – Turns the music video display on or off during gameplay only. Turning the movie display off will instead replace the music video with a graphic of the INFINITAS logo and text below that says ‘Sound Only.’


  • STANDARD – Standard mode in INFINITAS works closer to Free mode in older CS releases. All stages are counted as Extra Stages, you have no restrictions on what difficulty levels you can play, can repeat songs as much as you’d like, and there is no game over should you fail your song.
  • CLASS – Danintei/Class mode returns in INFINITAS, and carries courses from 7th Kyu all the way to Kaiden for both singles and doubles. Currently there is no gameplay benefit to attaining a higher rank outside of achievement rewards and bragging rights. Playing Class mode costs 1 play ticket per attempt.

How do I navigate the menus?

The game navigates pretty closely to previous AC/CS releases of beatmania IIDX, however, the game does do some things differently:

General Menu Controls:

Command Keyboard INFINITAS Controller
Move/Change L/R Ctrl, L/R Shift, Arrow Keys Turntable
Confirm Enter/White Key E1/White Key
Cancel Backspace/Black Key Black Key
End Menu Esc E4

Music Select:

Toggle Lane Cover Enter x2 E1 x2
Adjust Lane Cover Enter + Arrow Up/Down E1 + Turntable
Adjust Lift Enter + Arrow Up/Down E1 + Turntable
Quit Early Esc E2 + E3

How do I quit playing?

At any point in any of the game’s menus, you can quit by pressing Esc (or E4 on an INFINITAS controller) to open the end menu. You’ll be presented three options. In order from top to bottom;

  • Return to Title/Mode Select
  • Quit Game
  • Close the Menu

Any time you back out of Music Select with the first two options, you will be taken to the card out/log out screen and shown a summary of your play session. If you’ve earned any Achievement Mission rewards from your play, they will also be awarded here.

How do I unlock and use UI customizations?

All UI customization elements can be purchased with BITs via the e-Amusement Shop, linked in the upper right. Setting these can be done via the Customize link under the DJ DATA menu, and can be changed freely whenever you are logged in.

To change a UI element, click the blue button below the item you wish to change.

It will take you to a page that shows all of the available options you have for that particular element of the UI. Click the grey button below the one you wish to use, and you’ll be taken to a page confirming the change. As of this writing, you can change note explosion, turntable graphic, lane cover, notes, judgement font, full combo animation and key beams.

How do I use Rival Data?

Rival data is managed through the INFINITAS website. On the front page, hover over the DJ DATA link at the top to reveal links to various parts of the Rival system. Respectively, the first row is Index, Comment, Rival List, Rival Search and Reverse Rival Search. The second row is DJ Name, Customize, Tickets and Music. Note that you will need to be logged in to your Konami ID in order to access the portal.

Index is a summary of your personal data. Here, you’ll find your INFINITAS ID, class mode ranks, DJ Points, total BITS, and other info pertaining to your personal play data. It’s important to note that every INFINITAS player is assigned an ID number, formatted as C-XXXX-XXXX-XXXX. If you’re looking to add someone to your rival list, using their ID number this is the best and easiest way to do so.

Once you have your friend’s/rival’s ID number, or if you want to find a rival using other means, click Rival Search. This will bring up the rival search page.

You can search for rivals using a number of different criteria; INFINITAS ID, DJ Name, Area, DJ Points, class mode rank, players who have most recently logged in and played. If you have an ID to search with, you’ll want to enter it into the top field and then click the blue search button to the right of it. Otherwise, enter in the criteria for how you want to search in the fields provided and then click search to the right.

After you click search, the page will create a list of players that match what you searched for and a basic summary of each. Once you find the player you’re looking for, click their name to pull up their information page.

You’ll be presented with a quick rundown of their info, like your own Index page. Once you’re satisfied, click the ’Add Rival’ button at the bottom of the page. You’ll get a confirmation saying they’ve been added to your rival list, and a link to go to said list. However, you’re not quite done yet. The last step if you want to use their data in game is to set them as an active rival. To do this, you’ll want to go to your rival list by clicking on the link to your Rival list.

Here, you’ll find a list of all of the players you’ve added as rivals. However, in order to use their data in game, you’ll need to set them as an active rival. Active rivals appear in your in-game rival list, meaning you can race against their scores while you play songs and, if they add you as an active rival in turn, makes you both eligible to receive rival challenges from each other.

To set a rival as active, go to your rival list and click on the name of the rival you want to make active. On the next page below their data, you’ll notice that there is a pair of radio buttons for single play and double play, labelled ‘Active’ and ‘Not Active,’ along with two grey confirmation buttons; The first below the radio buttons applies changes to active/not active status, while the one at the bottom deletes the rival from your list.

You’re allowed to have up to five individual active rivals for both single play and double play, meaning you can have completely different active rival lists for both. To set someone as an active rival, click the active radio button on their page for whichever play mode you wish to make them a rival, and then click the confirm button below the options.

You’ll be shown a confirmation page confirming the changes were made. When you go back to your rival list, you’ll notice now that under SP and DP active on the list that there is a ‘○’ under the mode that you added them. If you see a double circle or ‘◎’ instead for that rival under your list, it means that you are mutual rivals and are eligible to send and receive rival challenges with each other for that play mode.

Another option you have for finding rivals is to see who has you listed as a rival. Clicking Reverse Search shows all players on INFINITAS who currently have you added to their active rivals list. From this list, you can add them back in the same way you’ve added someone to your Rival List by clicking their DJ name, and then repeating the same steps as listed above.

What are Rival Challenges?

Rival challenges are EX score challenges issued to and from your active rivals on your list that have mutually added you as a rival and also have you on their active list. These show up under a special red folder in music select labelled with kanji that reads ‘Rival Challenges’ below your Rival Win/Lose folders.

To issue a rival challenge to your rival, you must:

  • Beat your current best score (green graph)
  • Beat your rival’s best score (red graph)

Once you finish a song and meet both of the criteria above, your score will be sent to all of your active rivals with a lower score than yours as a challenge automatically. And the song, with your score, will appear in their rival challenge folder.

To attempt to beat a challenge, open your rival challenge folder and choose a song that you want to try to beat your rival’s score on. You’ll also notice that there’s an extra window that pops up while your rival challenge folder is open that shows which of your rivals owns the score, by how much they’re beating you in EX score, when the challenge showed up in your folder, and if the challenge is a ‘reverse,’ meaning it’s a score that your rival achieved from beating one of your challenges. Your rival challenge folder can hold up to 30 such challenges, and songs/challenges in this folder are removed either upon being successfully cleared, or if you receive a challenge beyond your 30th. In which case, the oldest challenge in your folder will be the first to be deleted to make room.

If you receive a challenge on a song that you currently do not have unlocked, you will be granted temporary access to the song and difficulty that the challenge is for, and your EX score and clear status will also be saved for songs played this way. However, you will be ineligible to receive Reward Mission rewards (detailed below), and once the challenge is either cleared or otherwise removed, your access to the song in Standard mode will be revoked until you unlock it.

Infinitas In-Game Currency and Unlock Process (new main section)

What are BITs?

BITs are the in-game currency for Beatmania IIDX INFINITAS. Similar to Dellars/FRICO/etc. in arcade releases, BITs allow you to unlock songs on the INFINITAS song wheel along with UI customization options through the e-Amuse portal. BITs cannot be purchased externally and can only be obtained by playing INFINITAS. How they are earned are (detailed here).

What are tickets?

INFINITAS Play Tickets are an optional in-game item that can be used to enhance your play session in INFINITAS and access other play modes. Tickets can be obtained either by purchasing them with Paseli, earning them through in-game events, or as a bonus as Konami decrees. They’re not required to play INFINITAS, but they do allow you to do more with the game.

Class Mode:

Class mode returns in INFINITAS and carries sizable BIT rewards for each course that you can clear. Both singles and doubles carry courses from 7th Kyu all the way to Kaiden and are tracked separately, meaning that you can earn BITS from the same course on both single and double. Outside of BIT rewards, Class mode rank has no impact on what you can play in Standard mode or any other aspect of the game at this time.

Bit Boost:

This option will double the BIT rewards you receive from repeat missions only for one hour. And, like the above option, costs one INFINITAS play ticket to activate. The timer starts immediately upon activating, and you will get boosts for each mission completed on the timer so long as the song that cleared the mission you’re currently attempting was started before the timer ran out.

Quick Refresh:

If you find yourself running out of repeat missions to complete, this option will allow you to immediately finish the cooldown on all of your repeat missions at the cost of one INFINITAS play ticket. If you have no repeat missions on cool down, this option will be greyed out and unselectable.

Mission Frames:

By default, you can only have one active mission at a time, but you can add up to two more active mission slots for 24 hours by using an INFINITAS play ticket for each one.

How do you earn BITs?

BITs are primarily earned through completing missions while playing INFINITAS, and missions come in three different types; Achievement Missions, Reward Missions, and Repeat Missions. Completing any mission will reward you with an amount of BITs corresponding to the difficulty of the mission. The harder the mission, the greater the BIT reward. See the “BITs Payout and Song details” for a detailed listing of missions and their payouts.

Achievement Missions

Achievement missions are awarded at the card out/log out screen at the end of a play session. These rewards are not repeatable, but do award sizable amounts of bits and are based typically on total cumulative play milestones.

Reward Missions

Reward Missions apply to each difficulty of every song (Normal, Hyper, Another), and are awarded upon a successful clear of the chart with the appropriate status on either singles or doubles. These rewards can stack with each other, (i.e. On your first play of 5.1.1. SPN, you get a full combo, so you get the bits for a normal clear, hard clear, ex hard clear and full combo clear all at the same time.) however, they can only be earned once and are not repeatable.

NORMAL 100 150 200 200
HYPER 150 200 250 250
ANOTHER 200 250 300 300

You can also quickly see what your mission status is at music select with the gauge that appears just above your score data window. This will show what clear status you have achieved on the highlighted song and difficulty, along with what clear statuses you have yet to achieve:

Repeat Missions

As their name implies, these missions can be repeated once every 22 hours. To earn any rewards from these missions, you must select the mission through the mission select panel.

Note that you are only awarded credit towards a mission if it is in one of your active frames. If a mission isn’t selected as one of your active missions, you will not make any progress towards it.

By default, you can only have one active mission at a time, but you can add up to two more active mission slots for 24 hours by using an INFINITAS play ticket for each one.

The game will also warn you when you have a mission frame without a mission with a pop up in the top center of the screen. If you see this, you should look at selecting a mission before proceeding to choose a song:

Konami also can award BITs through other means as they so choose, and can also deploy bonus rate events to the server, so pay attention to the official website and their Twitter account (@infinitas573) to watch for announcements on bonus BIT events! 

How Do I Get More Songs?

Songs in INFINITAS are locked individually as well as by each individual difficulty level, and depending on the song, can either be unlocked via earning a certain number of DJ points, purchasing individual difficulties with BITs, or by purchasing a song pack with money (PASELI or debit/credit card).

DJ Point Unlocks

The following songs are unlocked by achieving a certain number of DJ Points, and will unlock all three difficulty levels for play on both singles and doubles when successfully unlocked:

サヨナラ・ヘヴン 猫叉Master 200
The Story Begins SADA & Sota 400
Dazzlin’ Darlin-秋葉工房mix- Remixed by DJ Command 800
水上の提督(Short mix from “幻想水滸伝V”) 猫叉Master 1600
3y3s (Long Ver.) 青龍 3200

Monthly Subscriber Songs

On the first Tuesday of every month, Konami adds a minimum of 2 new songs to INFINITAS and the songs are announced both in-game as well as through the INFINITAS website and the game’s Twitter. These ‘subscriber loyalty’ songs come fully unlocked with all difficulties available for play and are exclusive to active subscribers. To claim these songs, you must have an active INFINITAS subscription and are required to log in and play Standard mode at least once during the month that they are released.

If you miss the above steps and fail to receive the monthly songs during the month that they are released to the INFINITAS network, then you must wait for them to become available for purchase with BITs.

BIT Unlocks

Songs purchasable with BITs are locked by each individual difficulty, meaning if you want to unlock all three difficulties for one song, you will need to buy access to all three charts. Thankfully, single and double play are unlocked together when a chart is purchased, so if you unlock a song in single play, its equivalent chart will also be unlocked in doubles play at the same time, and vice versa.

To unlock a song, go into Standard mode and highlight the song you wish to unlock on the music wheel. If it can be unlocked using BITs, it will have a pop up below the highlighted song showing both your current BIT total as well as the number of BITs needed to unlock the song. To confirm your unlock, press a white key or enter, and the game will ask you one more time to confirm your choice. Choose yes, and the song and difficulty you chose are now permanently unlocked for play, and the song’s cost in BITs will be deducted from your total.

The cost to unlock a song is determined by its combined difficulty level between singles and doubles. If no chart exists for either singles or doubles on a particular difficulty, it’s considered a 0 for the following formula:

Song Unlock Cost = (SP Level + DP Level) * 500

Example: 22DUNK on Normal is a 3 in single play and a 5 in double play. The cost then to unlock its Normal difficulty charts is 4000 BITs:

(3 + 5) * 500 = 4000

Song Packs

Konami also offers packs of songs to boost your song list for INFINITAS. These packs can only be purchased with PASELI, and permanently unlock all charts for the songs in each pack on both single play and doubles play. Each pack adds 30 songs with the exception of vol.1 which only adds 25, but also costs less. A detailed list of songpacks can be found here.

Achievement Missions

Total Plays:

  • 100 BITs for every 10 songs played (10-100 songs)
  • 550 BITs for every 50 songs played (150-1000 songs)
  • 1000 BITs for every 100 songs played (1100-5000 songs)
  • 5500 BITs for every 500 songs played (5500-10000 songs)

Total DJ Point:

Reward Missions

Reward Missions apply to each difficulty of every song (Normal, Hyper, Another), and are awarded upon a successful clear of the chart with the appropriate status on either singles or doubles. These rewards can stack with each other, (i.e., On your first play of 5.1.1. SPN, you get a full combo, so you get the bits for a normal clear, hard clear, ex hard clear and full combo clear all at the same time.) however, they can only be earned once and are not repeatable.

NORMAL 100 150 200 200
HYPER 150 200 250 250
ANOTHER 200 250 300 300

Repeat Missions

Music Play/Clear/Full Combo:

Missions in these categories run at intervals of 5, up to a maximum of 30. (i.e., 5, 10, 15, etc.) And the BIT reward associated with each individual mission can be simplified to a formula for each:

  • Music Play = 10 BITs x number of songs played
  • Music Clear = 40 BITs x number of songs cleared
  • Music Full Combo = 50 BITs x number of songs cleared

It’s important also to note that for these missions, the plays, clears or full combos do not need to be consecutive. You are allowed to fail or break your combo for the latter two mission types without having to worry about your count being reset.

DJ Level A/AA/AAA:

Awarded immediately upon clearing a song of the marked difficulty level or higher with the appropriate letter grade. If you earn the required DJ level or better than the grade the mission specifies, you will earn the reward.

LEVEL 1 100 150 200
LEVEL 2 150 200 250
LEVEL 3 200 250 300
LEVEL 4 250 300 350
LEVEL 5 300 350 400
LEVEL 6 350 400 450
LEVEL 7 400 450 500
LEVEL 8 450 500 550
LEVEL 9 500 550 600
LEVEL 10 550 600 650
LEVEL 11 600 650 700
LEVEL 12 650 700 750

 Great/Perfect Count:

These missions require you to hit a set amount of notes with either Great or Perfect Great timing. They operate in denominations of 500 for each up to 5000 for each judgement type. Like earlier missions, these are cumulative totals. And, for great count missions, Perfect Greats will count towards your total number of Greats. Mission awards are:

  • 100 BITs for every 500 Greats
  • 150 BITs for every 500 Perfect Greats

Class mode

Single play and double play are tracked separately, meaning you can earn bits from clearing the same course on both singles and doubles. However, a successful clear of a course will only reward the BITs for the class you cleared. You will not earn the BITs associated with the classes below the rank you cleared. (i.e., Clearing 6th Dan will not award you with rewards for 5th Dan and below) Playing class mode requires an INFINITAS play ticket for each attempt.

7th Kyu to 1st Kyu 5000
1st Dan to 10th Dan 10000
Chuuden 20000
Kaiden 30000

Frequently Asked Questions (FAQ)

Q: Can I play INFINITAS on a tablet PC or smartphone?
A: No, but there is a version of IIDX for mobile phones called Beatmania IIDX ULTIMATE MOBILE. You can find it on the Google Play store for Android and Japanese iTunes store for Apple devices.


Q: Can I transfer my scores to/from the arcade releases?
A: No, but according to their FAQ, Konami may change their minds someday.


Q: Can I change what keys are assigned to what button on my keyboard?
A: Yes. Open your options menu in Music Select and hit Backspace/E2 until you come to the key reassignment menu. From there, you can rebind which keys on your keyboard are used for any of your 14 keys, as well as the forward and back scratch buttons. System/option commands cannot be rebound. These can also be changed via the settings menu on the launcher


Q: The launcher won’t start the game.
A: Make sure your game files are up to date using the file checker and that your PC is connected to the internet and try again.

If your game still won’t boot and you have a sound card that is connected via PCI Express, it is a known issue that these sound cards aren’t recognized by the game. Try removing/disabling your sound card and restarting.


Q: I get a ‘Graphics Initialization Failed’ error when the game tries to start.
A: According to Konami, there are a few things that can be causing the problem:

  • Your graphics drivers are not up to date.
  • Your display configuration isn’t supported. (It must support 1280×720 @ 60 Hz)
  • Your computer’s graphics hardware does not meet the minimum requirements to run the game.


Q: I get error code 5-1505-0005 when I try to start the game.
A: This code means that the game can’t detect a sound output device. Make sure you have sound enabled on your computer, you have an output device enabled under your sound settings, and that you have speakers of some kind or a pair of headphones plugged in and try again.


Q: When I try to launch the game, everything goes dark and the game abruptly quits.
A: This happens when the game tries to initialize its network connection and is blocked either by a firewall or an antivirus program. You’ll want to register bm2dx.exe to your exception list for the offending software so it can launch and communicate properly with the e-Amusement servers.


Q: I get a ‘Network Boot Error’ and it shows code 5-1502-0042.
A: This means the game cannot connect to the e-Amusement servers, and has one of two solutions:

  • If it’s during a maintenance period, you’ll have to wait for it to be over.
  • The game’s connection is being interrupted/blocked by your firewall, and you’ll have to make an exception for it to get through.


Q: I get a pop up to enable sticky keys when I’m playing. Can I disable it?
A: Yes. Under your Windows Control Panel, go to accessibility settings > keyboard settings > uncheck ‘allow keyboard shortcut to start sticky keys’.


Q: When I’m playing songs, they gradually go out of sync with the background music.
A: Your graphics card may be causing the problem. Try playing the game with vertical sync enabled. Or, if you have vertical sync turned on, try turning it off.


Q: When I’m playing, the game abruptly stops and then resumes, and then everything is way off sync.
A: There’s a few things that can cause this to happen. Here’s what Konami says, and what I’ve found:

  • Konami recommends keeping the number of background applications running to a minimum while you’re playing, as things like email, anti-virus programs, Windows Update and programs that affect display and sound can interfere with the game running smoothly.
  • Your hard drive may be fragmented, corrupted, running out of space, or otherwise unable to keep up with the demands of the game.
  • If you’re using an onboard graphics card, you might be running out of memory. Consider increasing how much memory is allotted, or it may simply be time to upgrade your graphics card.
  • If you’re playing on a Wi-fi connection, I’ve found that this also can cause problems if a lot of people are using the connection at one time for things like Netflix, YouTube or other applications. Try running the game on a wired internet connection.


Q: There’s a lot of inconsistent timing with songs, and I can’t figure out why things aren’t consistent.
A: The solution is going to vary depending on why things are inconsistent. To figure that out, Konami recommends the following steps:

  1. Try playing the game on your display without any sound; Choose an easy chart that has a simple to follow rhythm and play using your keyboard. If your button presses aren’t lining up with what’s being shown, it means you have a laggy display. You can adjust this either by using the adjust timing option in the options menu, or by changing how your monitor is hooked up to your PC.
  2. If the timing fluctuates throughout the song, odds are that your computer is struggling to keep up with processing both game data as well as the song movie/graphics. Try turning movie display off in the options menu and play the song again. If this solves it, you may want to consider upgrading your graphics card.
  3. If the timing continues to be inconsistent throughout the song, even with the movie display turned off, it means that your computer is struggling to process game data. Try closing any excess applications running in the background and run the game again. If the problem persists, your PC may not meet the required minimum specs to run the game.
  4. If your timing is on sync with your keyboard but off sync with your controller, make sure your controller is plugged directly into your PC and not through a USB hub or similar. These can add delay to inputs.


Q: Why do my fonts look all screwed up and nothing like they do in the screenshots? Why do I have mojibake?
A: You need to change your non-Unicode program language to Japanese. This can be done in your control panel in Windows under the ‘Administrative’ tab of Region Settings.


Q: Why is the text missing from my initial log in notice window?

A: Even after changing your Unicode language and otherwise taking steps to try and prevent mojibake, some players have experienced the daily notice window (typically confirming you receiving your daily log in BIT bonus, announcing new sub songs are available, etc.) appearing but not having any text. This is just a cosmetic error and does not affect gameplay, being able to receive bonuses, etc. It can usually be fixed by setting your Windows 10 Region to Japan.


Q: I played INFINITAS on the old client prior to the 120Hz update. Does my save data transfer?
A: Yes. When you log into the new client for the first time, you will be prompted to transfer your save data from the old client to the new one. This transfer moves all of your score data, including detailed score info, clear lamps, unlocked songs, song packs purchased, INFINITAS Play tickets, class mode ranks and completion, and UI customization unlocks and settings. What does not transfer is your rival data settings, so you will need to re-establish your rivals and rival list if you had one. The transfer is also one way, meaning that once you move your data from the old client to the new client, your old client data will be erased and no longer usable.


Q: Does the new client only run in 120Hz?
A: No. The game can still run and function at 60 FPS if you don’t have a monitor that supports 120Hz. And you can choose what both your video and audio settings are in the launcher before you play. (See above.)


Q: What if I don’t want to upgrade to the 120Hz update. Can I still play on the old client?
A: For now, yes. Konami has stated that the old client will remain usable through February 25, 2021. After that, it will be decommissioned and shut down. If you purchased any play tickets or song packs prior to the release of the 120Hz update, they will still be usable in the old client, but any new purchases of song packs or tickets made after the 120Hz update will only be usable in the new client. In addition, all future content and updates will only be playable in the new client. This includes subscriber loyalty songs, BIT unlocks and song packs.

Play Tips & How to Make the Most of INFINITAS

It can be very daunting or even discouraging to try to pick up the game when you hear that ‘BITs are a grind’ or that you don’t have any friends or rivals that you can get into the game with. Below are some of the things that I’ve found that can help you earn BITs quickly.

You can get a lot of BITs early on by clearing Dan courses

Dan courses are a great way to earn a lot of BITs quickly early on to allow you to unlock the things you want with minimal effort. Each course, depending on the rank, pays out anywhere from 5,000 to 20,000 BITs upon being successfully cleared for the first time.

Don’t be afraid to use BIT Boosts, extra mission panels or Quick Refresh

When you don’t have any more Dan courses that you can clear, you can use all three of these to still earn lots of bits quickly. Extra mission panels last for 24 hours once they’re turned on, so depending on when you add them, you can split them across multiple days if you time it right with your schedule and when you plan to play. BIT Boosting can also be increased by Konami whenever there’s a special event, such as Golden Week, so keep an eye on when there’s an event running so you don’t miss out on a chance to take advantage of better than normal boosts! 

You can stack missions of the same type together

If you’re trying to make efficient use of your time and have additional mission panels unlocked, you can stack multiple missions of the same type together so that you make progress towards all three. A few good examples of this are choosing three ‘Perfect Great’ missions together; When you play through a song, your perfect great total will be added to all three of the missions you have active, so you’ll make progress towards all of them. This also applies to other mission types like DJ Level missions, meaning you can select DJ Level A for Levels 1, 2, 3, then clear a level 3 song with an A, which will then earn you the rewards for all three missions.
