I am a licensed owner of the GAMEEX software. I am trying to get it running with MAME on a Windows 7 x64 SP1 box. It sees all my MAME ROMs, but when I click Play This Game on any of them, it: 1. Displays the controls 2. The screen blanks for a moment 3. Returns to the game-specific screen with no kind of error I am guessing this is a MAME configuration issue. I've tried running with mame.exe and mame64.exe - neither will work. What else can I check? Thanks.
