I am currently trying to play GBA games using gpsp with a custom gamepad mapping. <i>A</i> on Xbox 360 Wireless should be mapped to GBA <i>A</i>, and <i>X</i> to <i>B</i>. Therefore, I re-mapped my buttons using the UI I get when running <i>/opt/retropie/emulators/gpsp/gpsp</i>. The re-mapped and saved button config is functional in the gpsp config menu even after exiting and re-launching it.
However, the Xbox-to-GBA button mapping within the games themselves still is what seems to be the default and my custom mapping is ignored.
I’d be glad to hear any solution or general suggestions, many thanks in advance!!
