It doesn't work on any given game at time. But at time it works on any game I choose. Let's just pick super mario all star for the sake of argument. I would play that on the train. I shut it off and come back home and try it again... doesn't work. Maybe an hour later... it's working again. The system/emu, not sure which one but maybe both, picks and chooses when it wants to load the game. Loading the emu isn't a problem. Loading the game is. When it doesn't load, I just get this black screen and I would have to shut off and restart the system. There's no error message or anything. There's the black screen and that's it. I can't get out of it by pressing start and select. I'm not familiar with clonekeen trick. I'll find out.
