I recently got a 32X and a model 2 genesis. The problem I have is that Knuckles Chatoix does not go past the title screen. The demo mode also seems to freeze the system. I did have this problem with virtua racing 32X but it seemed to have corrected itself. What is wrong with the game? I do not know if it is a pirate cart as it did come CIB to me from EBay. I also tested metal head and it works just fine as well.
