Okay, now this just doesn't sound right. Although you did get Illusion of Gaia and Super Mario World 2: Yoshi's Island to work by cleaning the cart, your MegaMan X2, MegaMan X3 and StarFox 2 cartridges should work. Did you clean those? If they're clean and they don't work, your RetroDuo Portable may be defective. I should be getting a RetroDuo Portable v2.0 to test at some point during the holidays, and while I don't have MegaMan X2 or MegaMan X3, I do have a few SuperFX games, namely StarFox, Stunt Race FX and the SuperFX 2-equipped Doom. I see no reason why those wouldn't work unless they're dirty or your RetroDuo Portable has a problem.
