I just bought a HORI Fighting Stick Mini 4. I’d be happy to contribute a joypad autoconfig file for it, but I can’t think of a game to test that autoconfig file against. Are there any games that actually use all 8 action buttons?
You would likely need a ps1 game. For example, when I play Soul Blade, I use the options menu to map other buttons to my throws and A+B+K, etc.
