Help with Co-Op Psx games

Hey, Been playing alot of old school games with my girl lately, and we are running outta ideas on games. I am not interested in games that have a 2 player vs mode, as she gets pissed and stops playing after a while of it. So far we played CTR (which was fun till we beat it in like 2 days) Diablo, Metal Slug X, and Gauntlet. I know there is more out there, but I cant for the life of me remember any that are good. Suggestions =)

time crisis if you have lightguns I think.

Thanks for the reply, but sadly no light guns here :'(

Games like DDR and Guitar Hero are always fun to play together with someone =p

Try car combat games like :Twisted Metal
Vigilante 8
Rogue Trip Vacation 2012

chocobo racing ;D nid just controler

Road Rash 3D -> Great Co-op mode
Army men games
Gauntlet
Street Fighter Zero/Alpha 3 -> If you've unlocked the two on one battles mode.

me nd my girlfriendplay lots of fighting gae but chocobo racing my girlfriend like alot try it out

Blaze and Blade: Eternal Quest. It's very similar to Diablo :)

Do you have an N64 or maybe a good emulator? Diddy Kong Rancing, Mario Kart, Goldeneye 007- these are all good games for two people. (: Sorry I can't be of much help, the majority of PSX games I've played were single player RPGs. ): You could try something like Tekken or maybe the first SSX (snowboarding - race/freestyle), if that one was for PSX.

hmm co op is hard to find, try worlds scariest police chases ;)
