Howard, there are a lot of decaffinated brands on the market that taste nearly as good as the real thing.

Vulcan, here are the PSX games that live on my cab:
Castlevania: SOTN
Crash Bandicoot 1, 2, 3
Spyro 1, 2 , 3
Soul Edge
Tekken 2, 3 (no interest in 1)
Tempest X (this is a must-have)
Dead or Alive
Jumping Flash
Resident Evil 2
Wipeout 1, 2, 3
There are a few others but those are my favorites.
I was disappointed that I couldn't get Bushido Blade to work on mine--not enough buttons to cover both pairs of shoulder buttons, which are needed for those games and not re-mappable.
Soul Edge is the best fighter IMO
Tempest X alone makes the PSX emulator worth setting up.
