I'm using the PAC layout for a layout of 4 systems. Atari 2600, colecovision, C64 and mame. The problem is is that when I highlight a system, it plays a video I downloaded, but when it plays ones choppy at first, then clears up, and another one is all messed up too. I'm using an i7 CPU so I doubt it's that. I'm running attract mode in mint Ubuntu.
