beatmania IIDX 27 Lighting Mode Information

Notes

!!! tip "" Booting the game in Lightning Mode requires a few things. To start off with, you will need to enable the -iidxtdj option in SpiceTools and you will also need to enable the Enable Lightning Mode patch.

In doing so, and subsequently every time you choose to switch between the two modes, you will want to delete everything inside your `dev/nvram` folder, and redo the setup process again with initializing the backup date, setting the clock, shop name, and the definition type.

SpiceTools as of 10/26/2020 has some updated features to work with this as well. Namely, the ability to toggle the Lightning Model subscreen via the `Toggle Subscreen` option in the Buttons tab. You can use your mouse to navigate the touchscreen as desired. Enter your pin, toggle buttons, etc.

SpiceCompanion has also as of 10/26/2020 added a brand new Screen feature as well. Using SpiceCompanion, you can receive the subscreen on your phone/tablet/etc and then use your device as a touch device for the subscreen. Do note that at this time it will not work while the game is running in windowed mode. If you run into performance issues, go to the settings tab to adjust things like the Screen Quality, Screen Threads, and Screen Divide, this feature is heavily dependent on connection and you will notice as you bump up the quality that the ping will increase as well. It may take some fiddling to find the most ideal settings for your setup.

Enabling Lighting Mode Patch

`I:stackwalker: 00000001805FC970 (bm2dx): (unknown): dll_entry_main`

Please enable the lightning mode patch in SpiceTool's patch manager.

Audio Related Crash

!!! tip "" If you get a stack trace in your log.txt that looks like this...

`exception raised: EXCEPTION_ACCESS_VIOLATION`

`[2020/10/22 18:20:21] I:signal: printing callstack`

`[2020/10/22 18:20:21] I:stackwalker: 000000018026E906 (bm2dx): (unknown): (unknown)`

For cab type 1 (LDJ), change your audio device to motherboard audio and/or use -audiobackend asio `-asiodriverid ... -audiodummy`

For cab type 2 (TDJ, with `-iidxtdj` or another means), you have a few options:

1) Use `-iidxasio "Driver Name Here"` to set the ASIO driver used by IIDX's own ASIO handler. (Does not work with all ASIO drivers, they designed it to work best with a specific revision of the XONAR SOUNCARD(64))

2) Use `-iidxsounddevice wasapi` to set IIDX to use WASAPI instead of its own ASIO handler.

3) Use `-iidxsounddevice wasapi` along with `-audiobackend asio ...` to have the game pipe audio through Spice's own ASIO handler which is more compatible with various ASIO drivers
