I would have to go through the ROMs again to see what glitches I have. Here are a couple off the top of my head. Qbert for Intellivision has a glitch where every time you clear a level, you'd lose a life. On Comix Zone for Sega Genesis, the main menu screen has the bottom half on top and the top half on the bottom. I know I also had some other Atari 5200 games that would just be black screen when you mounted them. In these cases, I've tested the same ROMs in other emulators and they worked fine. I've tried using different versions of MESSUI to see if that was the problem. On an older version, Comix Zone didn't have this glitch. On all the versions I tried, Intellivision's Qbert had the same problem. I had noticed on later versions of MESSUI, there were some games that would black screen when mounted that now work, like Intellivisions Demon Attack. I'm currently using version 0.163.
