Only problem is that hurts the fuck out of the disc drive motor. Not recommended.
No it doesn't, as long as you do it properly.
Really the Action Replay is the easiest option.
Doesn't let you boot backups, only bypasses the region lockout.
There was a small flurry of activity a while back where a few people claimed to have read the ring data, but obviously no one ever figured out how to write it—if that's even possible, since I don't think we know conclusively whether it's normal data or not.
Best that people did so far was writing the "trademark sega etc" thing at the far end of the disc, which has fuck all to do with the protection. And no, it cannot be read with a normal cd drive. However, we have dumps of the command list sent by the cd block when its reading the ring, and the modchips have been reverse engineered. No one managed to burn out that data though.
Best would be a modern HD loader... someone would need to reverse engineer the Virtual CD development device (which was exactly that, a HD loader).
Or do you want to replace the Saturn's firmware a la Xbox Linux/Homebrew Channel? I don't think anyone's done that with the Saturn yet.
Nope, it has bee already done, and chips are on sale. All it does is bypass the region lock though.
