When booting the game with Forge 1.20.1-0.6.16 it boots fine, once I add Controllable 1.20..1-0.20.3 it crashes on the loading screen and displays this error:

The game crashed whilst rendering overlay
Error: java.lang.RuntimeException: java.lang.UnsatisfiedLinkError: Error looking up function 'SDL_GameControllerGetSensorDataWithTimestamp': The specified procedure could not be found.

Exit Code -1

Just found the Crash Report (sorry new to this)

Same issue. Installed sdl2-2.24.1, SteamOS

Same Issue. Any idea on this @MrCrayfish?

I faced same problem but it was not related to this project
I just googled it and found an issue here.

Then i solved this error by downloading sdl2.dll and plancing the file into the C:\Windows\System32 folder

You can download sdl2.dll here https://github.com/libsdl-org/SDL/releases

For windows users, choose SDL2-2.28.5-win32-x64.zip

I hope this will be helpful to you
