I just got a copy of the 12/06 MAMEoX. This is the first MAME on this machine as far as I know. It was working fine for me (some roms didn't work but I know how that is). I turn off my Xbox, go out to dinner, launch it and it freezes... The start up screen is even animated until I hit a button on my controller, then it freezes. Any suggestions would be greatly appreciated, I was just starting to get excited about my progress for a MAME/Media Center Cabinet.
