Resetting button cofig?

[Jappo]

I don't know how, I somehow messed up, I tried options > reset to default, but all that did was change my screen size. Any help?

On what? Mame? if so, delete the mame config file. it'll restore all mame settings to defaults.

yeah, delete that or if you're using kawaks or other, fba or nebula, simply delete the games .ini file and the buttons config will be reset
