If you like Stunt Race FX, you'll like this modification. The overclocked Super FX chip in the cartridge provides a much smoother frame rate. It's the only way to play this game. No other aspect of the game is changed. Works on any SNES!
Cart is in good shape with "24 MHz" written on it to help me distinguish this cart from a normal cart. I no longer have a SNES, so it's of no use to me.
$8 shipped in the US.
