Button setup for Xmame on RG350M

[Ben Sarconi]

I think I might have messed up a setting on Xmame for my RG350M because now while I'm playing any of the games, when I hit the A button, a menu Keeps trying to open up...How do I fix that? See the pic...

We've not really looked too much into xmame, but it might simply be worth doing a reinstall of the firmware.
Did you manually change the button mappings at any point?
