Well, for Yong Yong's first two bootleg games, they're about as poorly programmed as Cheetahmen 2, or Action 52 (Active Enterprises).
I've always tried doing so, but I've always made the ROMs worse. Now I will have to say, compared to most games (on GameBoy), they actually make the Super GameBoy run 4% faster. But here, Yong Yong screwed up the programming of these games, it actually plays at the same speed as the GameBoy consoles. Now I know they're bootleg games, but still... Also, these games are VERY unfair, because another part of the poor programming, like Sonic will fall off a platform VERY easily. It's extremely hard to play these games, without save states on an emulator, just because of cheap problems. But that's my point, Yong Yong perfected a good bit of the problems in later games like, Pokemon Adventure, and Super Mario Special 3.
So, could any of you help me out? Can you help try to tell me what I can fix out? ROM downloads:

(Yes, they're safe. They have no viruses.)
Now, I'm aware this isn't a topic that would be suitable for this website, but I'm doing this, to ask any of you the really technical details of what needs to be fixed.
