Loader

So I was digging around to figure out how I was going to boot a CD from my MPEG BIOS menu thing.
I found what I was looking for, and thought maybe it might help with your table compatibility issues too, if that's what they are. I note that at least one incompatible game (Skeleton Warriors) actually re-auths the CD at the logo screen, and I guess I wouldn't be surprised if a few others do too. I did manage to boot one of the reportedly nonworking games, but I haven't tested it against your loader - the laser on my Saturn is just about dead... I've had to wind the laser current pot all the way up and it still doesn't handle CD-Rs.

The commit notes on the loader commit explain what's going on. You need the patches I pushed to my Iapetus fork for the BIOS calls (sent you a PR on that too).
