Volume works fine for me.
Great app by the way!
I was wondering... further down the track do you aim to incorporate all the separate .app files into one main .app file? This would be awesome if possible. Also, I wouldn't mind seeing the coin button changed to just select on its own. Aside from that the only issue I have is not being able to re-define keys.
Many roms play fine for me & I really appreciate all the work that went into this, cheers!
