I rememeber trying to blow into NES and SNES cardridges for 10 mins just to get the game to work. Changing discs is easy peasy.
Try loading the same game from tape 4 times, hoping it will survive the wrinkle in the tape at 8 minutes this time. It could take half an hour to get hyper rally to work. Cotton swabs and alcohol at the ready to keep the tape heads clean. Still worth it.
