      • To uninstall Omnimix in case you don't want it, simply delete the Omnimix folder.
   3. To fix incorrect difficulties in DP omnimix charts, replace \Omnimix\info\0\music_omni.bin with the downloaded music_omni.bin

Tweaks

7. In the /prop/ea3-config.xml, change the version number to 2023090500. It should look like this:
   
   ⎗

   ✓

   1	<ext __type="str">2023090500</ext>

8. In order to launch the game properly, open avs-config.xml in prop folder and remove the following lines:
   

   ⎗

   ✓

   1 2	<vfs name="boot" fstype="fs" src="D:/LDJ/contents/dev/raw" dst="/dev/raw" opt="vf=1,posix=1"/> <vfs name="boot" fstype="fs" src="D:/LDJ/contents/dev/nvram" dst="/dev/nvram2" opt="vf=0,posix=1"/>

   and replace with:
   

   ⎗

   ✓

   1 2	<vfs name="boot" fstype="fs" src="dev/raw" dst="/dev/raw" opt="vf=1,posix=1"/> <vfs name="boot" fstype="fs" src="dev/nvram" dst="/dev/nvram" opt="vf=1,posix=1"/>

9. To get extra game features, head over to the patcher and select your bm2dx.dll in modules folder (be sure to make a backup copy first). Here are the following recommended options for you to enable:
   • Standard/Menu & Premium Free Timer Freeze (freezes the song selection's timer.)
   • Cursor Lock (after finishing the song, the song selection screen will take you to that last played song instead of the end of a folder every time.)
   • Unlock All Songs and Charts (optional)
   • CS-style Song Start Delay
   • Skip CAMERA DEVICE ERROR Prompt (you can also disable camera device in spicecfg.)
   • Force Max V-Discs (optional)
   • Enable 1P & 2P Premium Free
   • Enable BPL BATTLE
   • Quick Retry (hold both EFFECT & VEFX buttons to restart the song.)
   • Disable Volume Change (by default, your volume gets automatically changed to 100% upon launching spice. This option fixes that issue.)
   • Omnimix

10. Open up the sound control panel on Windows > Playback tab > Right-click on whichever is your default speaker > Properties > Advanced tab > Enable "Allow applications to take exclusive control of this device" and "Give exclusive mode applications priority" options to avoid game crash and fix music timing issues. Make sure it supports 16bit 44100hz (you'll be playing on WASAPI exclusive mode by default.)
11. To avoid the music syncing problem, open up the NVIDIA control panel and do the following:
    1. In the “Adjust Image Settings with Preview” page, enable “Use the advanced 3D image settings” option.
    2. Click on “Take me there."
    3. In the “Manage 3D Settings” page, click on the Program Settings tab.
    4. Select your spice64.exe
    5. Click to see recommended settings
       • It's worth reading "Optimize PC for Infinitas" guide as it is good optimization tutorial not just for Infinitas, but data as well. For now, just change 3D settings in NVIDIA control panel accordingly and don't optimize any further unless you still encounter syncing issues.
    6. Hit apply button.

12. Turn off read-only option on the contents folder to avoid getting unexpected issues.

Spicecfg settings

13. Open spicecfg.exe, and in Buttons tab, set your buttons (including Test, P1 1-7 [P2 if you are the right side player], Start, Effect, Vefx, etc.)
14. If you plan to use the IIDX controller, switch to HID mode on your controller, go to the Analogs tab and bind the turntable. From there, you can tune the sensitivity to your liking.

15. Go to the Cards tab and click the Generate button on either P1 or P2. This will create card0.txt in your contents folder, as that card will be used for logging in your EA profile in Asphyxia.
16. To have the game connect to Asphyxia, go to the Options tab and set the EA Service URL to http://localhost:8083

In-game setup

17. Open asphyxia-core-win-x64.exe for starting up your server, then spice64.exe to launch the game.

18. Wait til you come across the Backup data error message. Press the Test button to let the game generate backup data for you, and press the Test button again when you come across the Clock error (It means you have to set up your own time in-game.) You should be taken to the test menu screen.

19. Go to Network Options, configure the shop name setting to whatever name you desire if It's empty and test the network.

20. Go to Sound Options and test the game audio.

21. Go to Clock, save & exit to set time.
22. Tweak the rest of settings to your own liking.
23. When you're done, exit the test menu by selecting the Game Mode, which should take you to the game.
24. Press the Keypad Insert Card button to load up account creation.
25. You can go back to the test menu at any time by pressing the Test button. That's it for this guide, enjoy playing IIDX RESIDENT :)

FAQ

Where can I find resources that can help me get started in IIDX?

You can find everything you need to know about IIDX in IIDX.org.

How to get 120 FPS? (Only for 120hz+ monitor)

Enable the following options in the patcher:

• Force Custom Timing and Adapter Mode in LDJ.
• 120 FPS in all section (also includes in Skip Monitor Check FPS section if enabled.)
• Skip Monitor Check (optional, but not recommended enabling it unless the game runs at stable 120 FPS.)

How to customize note skins, lane cover, etc.

Go to http://localhost:8083/ after you open up asphyxia-core-x64.exe.
Click on IIDX under plugins on the sidebar > Profiles > Details > Settings > Tweak options to your liking > Hit Submit.

What's the difference between TDJ and LDJ?

TDJ mode has 120 FPS support and a secondary screen for accessing additional features like a search bar for songs, playlist, etc. This mode is used in the Lightning model and can be enabled in spicecfg. Note that you have to use Numpad on the subscreen instead of your keyboard.

LDJ mode has 60 FPS support, but no secondary screen. This mode is used in older IIDX model and your game will be set to this default mode if this is your first time installing IIDX.

How to launch a game in TDJ mode?

Do the following for enabling TDJ:

1. Enable TDJ mode in spicecfg (latest version)
2. Don't disable the subscreen and don't enable the single monitor mode in spicecfg & patcher.
3. Enable Bypass Lightning Monitor Error, Lightning Mode Camera Crash Fix, and Force TDJ mode in the patcher (not all options are available depending on what IIDX version you have installed.)

Launching subscreen in three ways:

• To activate the subscreen window on a main screen, press the Toggle Subscreen button (can be bound in spicecfg), and use your mouse to interact on the subscreen. Only one monitor needed.
• To use a secondary monitor as a subscreen, the monitor has to support at least 1280x720@60hz and have touchscreen support.
  • If your secondary monitor's resolution doesn't match the above requirement, you can fix this by enabling GPU resolution scaling for that monitor in the NVIDIA control panel or other similar program. Recommended to only have 2 monitors turned on at a time.
• Use the SpiceCompanion app on Android or IOS to hook up subscreen display on a tablet. To set up that app, do the following steps:
  1. Open spicecfg and go to options tab, set an API port and optionally a password.
  2. Open the spicecompanion app and enter your computer’s IPv4 address (which can be found by entering ipconfig in a command prompt) & port you set in spicecfg.

If you still cannot launch TDJ mode, delete the first Japanese line and the whitespace in the second line on ea3-config.xml at the prop folder (do this as a last resort.)

How to transfer a profile from the older IIDX to a newer one?

Move both savedata folder and card0.txt from the older IIDX to a newer one, and then type the same card number in the cards tab on spicecfg.

How to update IIDX?

To update the game to latest version, here's an example of how you upgrade the game's version in the following steps:

1. Apply 20221025 update on top of 20221019 and overwrite all files, it will then upgrade the game's version to 20221025.
2. Apply 20221031 update on top of 20221025 and overwrite all files, it will then upgrade the game's version to 20221031.
3. And so on…

How to manually change the version number in-game?

In the /prop/ea3-config.xml, change the version number to whichever version you have installed. Let's say It's 2023090500 for example, It should look like this:

1

<ext __type="str">2023090500</ext>

What's the difference between n-0 and n-1?

n-0 means unreleased data, whereas n-1 means current or past data.

Troubleshooting

Performance issues

• Optimize PC for Infinitas and data
• spice2x Optimization

Network error

Please check the following:

• Ensure your spice & Asphyxia server isn't blocked by a firewall.
• Have a game folder's read-only option disabled.
• Use the latest version of Asphyxia plugin that supports whichever IIDX version you have installed.
• Use latest versions of spice2x and Asphyxia.
• You have set correct EA service URL in spicecfg.
• Unticked the -ea option in spicecfg. That option is there if you want to get past the network check and play the game offline.

If you still get a same issue, go to ea3-config.xml in prop folder and replace what's in <services> under <network> with the following lines (do this as last resort):

1
2

<services>http://localhost:8083</services>
<services_localstrap__type="str">http://localhost:8083</services_localstrap>

I can only press 6 keys or less at a same time

This is known as ghosting and It's a common problem among all office keyboards. What you want is a keyboard designed for anti-ghosting, as almost all mechanical keyboards will have this feature built-in.

Alternatively, you can use two office keyboards simultaneously to be able to press more than 6 keys.

No audio is captured when recording IIDX with OBS, Discord, etc.

Enable the WASAPI shared mode in patcher and set your audio device to 44100 Hz.

IIDX doesn't capture my controller inputs

Check your bindings on spicecfg and ensure there aren't any controls marked as Device missing. If so, rebind them.

Alternatively, you can use AntiMicroX to map your controller inputs into keyboard presses.

Audio issues

##### log.txt (audio crash) #####
W:audio::wasapi: WrappedIAudioClient::IsFormatSupported failed, hr=0x88890008
W:SuperstepSound: Audio device is not available!!!

• Method One (WASAPI):
  • If you set the game to use exclusive audio (by default, the game uses exclusive audio), then ensure your audio device can support exclusive mode at 44100 Hz. Be sure to enable "Allow applications to take exclusive control of this device" and "Give exclusive mode applications priority" options on the advanced tab in a sound properties window.
  • If you've enabled WASAPI shared mode in patcher, set your audio device to 44100 Hz.
  • If 44100 Hz isn't available in your audio device, try connecting the USB DAC.
• Method Two (ASIO):
  • If 44100 Hz isn't available in your audio device, or that you're using an older CPU that doesn't supports SSE 4.2 & have enabled the SSE 4.2 Fix option in the patcher, you can route the speaker through ASIO4ALL program, then make sure to set -iidxsounddevice option to asio and -iidxasio to ASIO4ALL in spicecfg.
    • Alternatively, you could use FlexASIO if you prefer more customizability than what ASIO4ALL has to offer, then simply set -iidxsounddevice to asio and -iidxasio to FlexASIO

W:libutils: 'C:\LDJ\contents\libavs-win64.dll (or bm2dx.dll)' couldn't be loaded

This error in log.txt usually occurs if there are DLLs in the game folder. Make sure that those are in the modules folder.
