beatmania IIDX 31 EPOLIS

Please make sure you downloaded your data from an appropriate source.
This guide is unable to troubleshoot any problems related to bad or poorly managed data.

About data

The full game should be around 100gb while updates are only around 2-5gb in size.

Standard (LDJ) / Lightning (TDJ)

Please keep the following in mind as you're going through this guide.

IIDX's codename is LDJ. For IIDX 31 Epolis this would be either:

  • LDJ-010 (TDJ, Lightning cab, 120 FPS)
  • LDJ-012 (LDJ, Standard cab, 60 FPS)

The main difference between 010 and 012 is the game's main .dll file, bm2dx.dll.

This changes which features the game offers, and which conditions the game expects to run under.

  • TDJ expects a 120hz compatible monitor for its main screen, and a second 60hz touchscreen compatible monitor called a subscreen. The second monitor isn't mandatory, we can get around that using spice2x.
  • LDJ expects 60hz monitor for its main screen, and no subscreen.

We'll be using the terms TDJ for Lightning, and LDJ for Standard throughout the guide.

If you're coming from IIDX 30 Resident

You'll want to update your data from LDJ-003 to LDJ-010 or LDJ-012 FIRST then follow this guide as normal.

Preparing data

After downloading and extracting your data, we need to make sure your files aren't set to Read-only.

  • Right click the folder containing your data, then click on Properties.
  • In the General tab go down to Attributes, untick Read-only and click Apply.
  • A popup will appear, select Apply changes to this folder, subfolder and files and press OK.
  • Finally, click OK again to exit out of properties.

You should end up with a file structure with a few folders only, as follows.

If your data doesn't look like this

If you're missing the modules folder and instead have bunch of .dll files next to your folders:

  • Create a modules folder.
  • Move all .dll files inside of it so you end up with a structure as shown above.

If extra files are present next to your folders, such as executables, scripts, etc.. remove them.
This also means your data was tampered with and we strongly recommend getting new data from somewhere else.

If you don't need to update your data, you can skip over to the Installing Spice2x section.

Updating data

Please make sure you're using the right update for your current data.

As we've seen in the About data section, the main difference between LDJ and TDJ is the bm2dx.dll file.
When updating from a previous version to the next, our current .dll will be overwritten.

Knowing that, patches re-uploaded by the community tend to be named LDJ-DATECODE-to-LDJ-010/012-DATECODE.
Note: If updating from IIDX 30 Resident, it will be LDJ-003-DATECODE-to-LDJ-010/012-DATECODE.

For example LDJ-2024032500-to-LDJ-010-2024050700.

  • 2024032500 being your current data's version, no matter if it's using a TDJ or LDJ .dll file.
  • 2024050700 being the version you would arrive at.
  • 010 meaning you would end up with a TDJ (Lightning Cab) bm2dx.dll file.
  • Extract your patch's files to your existing data in a way that matches its file structure. Agree to overwrite files if necessary.
  • Open prop\ea3-config.xml in a text editor and find the following lines near the top.
    <soft>
        <model __type="str">LDJ</model>
        <dest __type="str">J</dest>
        <spec __type="str">E</spec>
        <rev __type="str">A</rev>
        <ext __type="str">2024050700</ext>
    </soft>

On the line with <spec __type="str"> the letter needs to match your data type:

  • E for Standard (LDJ-012, LDJ, 60hz)
  • D for Lightning (LDJ-010, TDJ, 120hz)

Replace the letter accordingly if necessary.

On the line with <ext __type="str"> the datecode needs to match your new version.

  • If that's already the case then great! Don't touch anything.
  • If it instead corresponds to our pre-patch datecode, replace it with the new one.

Now save the file.

Installing Spice2x

  • Head over to spice2x.github.io and download the latest release.
  • Extract the spice64.exe and spicecfg.exe files from the archive to your game's directory.

Configuring Spice2x

Open spicecfg.exe, each following sub-section corresponds to a tab at the top.

Buttons

Click on Bind then press the key you want associated with the action.

With your controller and/or keyboard plugged in, configure your keys for:

  • Maintenance: Service, Test
  • P1 Game buttons: 1 to 7, Start, EFFECT, VEFX
  • P1 Keypad: Keypad Insert Card

Only if you're using LDJ:

  • P1 Keypad: 1 to 9

Only if you're playing using a keyboard:

  • Turntable: TT+, TT- and optionally TT+/- which alternates between TT+ and TT- on each press.

Analogs (controller/cab only)

With a controller rather than binding buttons to TT+ and TT-, you need to:

  • For Turntable P1, click Bind.
  • In Device, pick your controller.
  • In Control, pick whichever one corresponds to the turntable.
  • Turn your turntable ensuring that the Preview turns along with it.
  • Click Close, leaving the rest of the settings alone.

Overlay

Modifying buttons in this section is not required but you are free to change what you want.

Click on Bind then press the key you want associated with the action.

Lights (controller/cab only)

Your controller might support having its lights controlled by the game through spice2x.

If it does, here's how you may link different actions to your lights:

  • Click Bind.
  • In Device, pick your controller.
  • In Light Control, select the corresponding light.
  • Click Close.
  • Repeat for your other lights.

Cards

Covered in the Connecting to a network section.

Patches

First go through the Spice2x Patching page to import patches.

If not using ASIO, you NEED to patch Force Audio Output Mode to WASAPI otherwise the game won't boot.

Other patches that may be useful to you

Note: As a general rule of thumb, the fewer patches the better. If you're unsure what something does, don't enable or change it.

Patch Recommendation Description
Force TDJ Mode Either Starts the game in TDJ (010) mode when using a LDJ (012) .dll file. Use this instead of forcing 120Hz using other patches.
Standard/Menu Timer Freeze Either Freezes the timer in all non-premium environments.
Premium Free Timer Freeze Either Freezes the timer in Premium Free mode.
Cursor Lock Either In song select, always returns to the previously selected song.
CS-style Song Start Delay Either At the start of a song, holding Start will pause it until you release it.
Increase Game Volume Either Ignores in-game settings and keeps the volume at a maximum, helpful for TDJ which tends to be quiet.
Hide all bottom text Either Hides text at the bottom of the screen such as Credits or Paseli.

API

Leave everything at default unless you know what you're doing.

Options

If you don't know what an option does, hover over the question mark at the very left.

Be very careful changing options you don't understand as it may cause issues.

Required

Category Option Parameter Setting
Game Options IIDX Disable Cameras -iidxdisablecams ON
Network EA Service URL -url Covered in Connecting to a network

Required For TDJ

Category Option Parameter Setting
Game Options IIDX TDJ Mode -iidxtdj ON

If you only have a single 120hz monitor, and not another 60hz touchscreen:

Category Option Parameter Setting

Advanced & Development

Leave everything at default unless you know what you're doing.

Connecting to a network

Please choose one of the two solutions, not both!

Remote (Online Network)

Open spicecfg.exe and head to the Options tab.

In the Network category, set the following settings:

  • EA Service URL to the URL provided by your network.
  • PCBID to the PCBID provided by your network.

Next you need a card number.
If you don't already have one, generate one in the Cards tab.
To keep your card number safe, create a new .txt file with ONLY it inside.

Once that's done, head to the Cards tab, for Player 1 click Open... and point to your text file.

Local e-amuse Emulator (Asphyxia)

This is covered in the Asphyxia CORE page.

Pre-launch requirements

These steps are required, otherwise your game won't run.
