Always attempt to dump your own BIOS from your personal hardware. If you cannot, tread carefully in the legal grey zones. And when you finally hear that deep, resonant "Sega Saturn" jingle through your emulator, know that you've unlocked a crucial piece of gaming history.

However, this has never been tested in court. sega saturn bios mpr17933bin
