Yes, I'm still banging the Alien Trilogy drum
Saturn reverse engineer 'Bo' recently took a look at Trilogy and found a few extra undocumented passwords.
It's not quite as exciting as it sounds though. Basically, the cheat sites list a cheat menu for the PSX version and individual cheat passwords for the Saturn version. It turns out both ports have both types of code. The Saturn cheat menu password is a bit rude which presumably explains why it was never released and publicised like the other codes.
