psx patches

[davewizz]

Does anyone know where to get psx patches that actually work?I've tried ones from gamecopy world and also tried patches by kalisto,BAD Paradox and others that I've found on the net, none have worked for games such as Toca World Touring Cars,Crash Team Racing,Soul Reaver, I could go on but won't. It's a real pain to keep wasting discs.
So far only Gran Turismo 2 has worked but that just modifies the game with having nothing to do with removing the protection. It's very disappointing to be told that the patching is successful and to have fun but you can't when it doesn't patch it correctly.
Any help would really be appreciated.
Thanx
Dave
