nOOb 2 PSX burning need help!

[Merc]

OK, today, i burned my first playstation disk. It was just the gameshark on cd that comes from this site. Now, i've burned DC games and have never had trouble with them. I don't quite understand how to get PSX games to work without a mod-chip. I do know that you can hold down the button so the door can stay open, but i got nothing else besides old swap tricks. i can't get it to load even then. can it be done without a mod-chip!? oh yeah. this is one of the original psx's so it's still got it ports on the back for old gamesharks.
