I was trying to get Pico-8 (a fantasy console that you may already own from the Bundle for Racial Justice and Equality from 2 years ago) to work on my ALP.

It wasn't recognizing my Arcade Control Panel as a controller though.

I used General Arcade's GamepadTool (available for for Windows, Mac and Linux) to map the buttons.

Then, I clicked "Copy Mapping String" to copy the mapping string to the clipboard.

Then, I found sdl_controllers.txt and pasted the mapping string there (after the line stating that is what you should do there).

I'd recommend closing PICO-8 before editing the file, just in case it overwrites the file while open. You can find the file here:

• Windows: C:/Users/Yourname/AppData/Roaming/pico-8/config.txt
• Mac OS X: /Users/Yourname/Library/Application Support/pico-8/config.txt
• Linux: ~/.lexaloffle/pico-8/config.txt

I used https://pico-8.fandom.com/wiki/Controllers to figure this all out.

I assume, but don't know for sure, that this would also work on the Legends Ultimate. I don't own one though.
