As impressive as FCE Ultra GX is, I don't understand why the most important thing had never been fixed. Curious why some games don't work? try playing games like Baby Boomer and Gumshoe and see the corrupted graphics. Now try loading the Action 52 game and then loading Baby Boomer or Gumshoe... WOW, they work now. The same can be done for dozens of other games, it's just like a puzzle trying to figure out which game to load first in order to make others work. I've never written an emulator but I'm told that this happens because emulators do not clear memory or CPU registers before launching a game. On a real NES you power the system off between loading the games, that's why you never have a problem there. Now after years of waiting for someone to consider this all I can only say... SERIOUSLY guys? this is all it takes to fix the problems and nobody will do it? I would if I knew C++. If someone can get this suggestion to the developer we might actually fix a lot of games.
