I have a strange problem with the Pac-Man Collection cart on one of my two 7800s. It crashes and doesn't boot up past the initial Atari screen, or if it does get past that screen, it'll either freeze up, and show garbage graphics. I have an older model 7800 (one with the expansion port on the side), and it works fine on that one. I don't think this would have anything to do with it, but I should note that I recently did the RCA composite upgrade on the 7800 that it crashes on, and the other 7800 that it plays fine on still uses the RF connection. All the other games- both 7800 and 2600 work fine on both 7800s, including the games with the pokey audio. Is there anybody else who has had trouble with the Pac-man Collection game crashing, or could this just be a bad cart? If so, I don't understand why it would play fine on one 7800, but not on the other. Thanks
