ok newb here please dont laugh.
I'm in the middle of making a MAME cab from a gutted out NEO GEO cab. While I was in the middle of the game testing the controls the in game MAME menu appeared. I must have hit 'tab' somewhere. I was trying to reconfigure to my liking and I am pretty sure I accidentally hit 'none' under menu button. Now my player 1 'up' doesn't function and the in game menu doesn't function. How can I prompt the in game menu without the tab button? is it even possible? Ive been trying for almost an hour now and there are no buttons that work.
thanks in advance
