Just for conversation, the original Toejam & Earl game is corrupt from those two sites unless they fixed it. I tried it. But I have managed to find a working one if you want it. I still have lots of Sega Genesis Roms, but not as many as SNES.
Theme Park is no good either. I wanted a fully working SNES or Genesis version, but the Genesis version has no sound and SNES has scrambled graphics.
