Hmm, never heard of that much trouble with MAME before...

It might have accidentally changed the button to bring up the menu? If so you can erase the default.cfg somewhere around the MAME directory, other than that, MAME is pretty much a piece of cake.

Yeah man, lol I touched something by accident, then this screen came up.I have had MAME for a few months but only started to try playing it recently and I'm still a newb with it.So, forgive me.I'm not familiar with it at all.

Others have told me about ZSNES but that's UMK3, check told me that is also fun even though it's not MAME's arcade UMK3.I'll play any just as long as my configuration works once I figure it out.
