For those of you who want to play backups of some of your classic Sega Saturn games, but don’t want to mod your machine, you need to learn how to perform the swap trick. This involves using an original copy of any Saturn game and then swapping in the backup disk before the machine knows what’s going on. For more details, check out these helpful links.
I must admit, the swap trick isn’t especially easy. If you have a model 2 Saturn (round buttons) it is a major pain. If you are only going to be doing it a few times on a Model 1 (oval buttons) it’s bearable. However, if you’re going to be playing burned discs on normal basis, save yourself some grief and get a mod chip.
