Lakka and MAME

So i got mame working on Lakka. It plays games well and what not, but what i’m having issues with is that i pressed the right trigger on my Xbox controller. it went to the debug menu. i went into Input (general) and deleted the input value for a key on accident. I can’t figure out how to rebind this. Thanks in advance.

Is there a way i can just reset the config for mame in lakka? I really just derp’d it up now.

ok i solved the issue by deleting the config files. but here’s another weird thing thats happening to me. Anytime I press Y on my controller, it makes player 2 spawn in. Why?

Pitiful self bump

I forget which button does it (tab?) but you can go into the MAME OSD menu and map/unmap the default mappings in there. I think that’ll let you do what you’re trying to do.
