I’m in a similar boat as prusr. I copied your config Zoot, and everything was working fine in my other emulators, except my start button wasn’t working in MAME. So I ran the Input Configuration again, and then went into the config and added:
input_enable_hotkey_btn = 8 input_exit_emulator_btn = 9
And now my dpad doesn’t work. I’m going to try removing them and see what happens when I get home from work.
