Question about setting controls

I have a bit of a problem. The defualt button to adjust controls is set to tab, but somehow I changed this, and now I have no idea what button I use to set my controls. I went through all the keys on my keyboard but none of them worked. My question is: Is there a way to reset mame to have tab return to being the key to set controls, or should I just reinstall mame?

What emu? If it’s mame, somewhere in the main folder or one of the sub folders, there will be a “default.cfg” file. (In regular mame, it’s in the cfg folder; in mame32k, it’s in the cfgwin folder.) Delete default.cfg. When you start a new game, it will be re-created, with defaults.

What he said :tup:

yes its mame32, thanks :tup:
