If you play online you have to unlock them every time because it doesn't look at the file info that is made for the game when you do, it's like it starts it up fresh everytime, which is why options for the games like slow timer, turbo 2, manual only, free play, all get reset everytime you play online, but stay offline. Also, make sure that Mame doesn't crash or anything, so when you unlock all 3, close mame and that will keep them there.

On a somewhat related note, Final Burn, if you played online you couldn't change options, and it would also revert them to defaults offline, yet they stay if you never play online. Very annoying.
