Okay, I just turned off all of the game filters and what not that hide some of the games. I now have my centipede rom coming up on the list , which is good, but when i open it, it acts as if it is loading then will return back to gameex. This is not the only game that does it, i believe alot of the pacman games do the same thing. They were working fine before i started using gamex, but then again i switched to the new build of mame at the same time i switched to gameex. I really dont know what could be the problem. Im not saying that it is gameex's fault, but maybe someone out here knows whats up. Thanks guys, ps: great program -Kyle
