[Cypress Hill]

Alright, i've been downloading alot of so called PSX emulators and they don't work at all! can't find bleem, and when i think i got it it says not an valid win32 app...screw that!

Anyway, i just saw that i got a Copy of Tenchu2 here, and i really wanna play that game if possible, didn't know i still had it! so what's a good Emu to use for PSX on PC in Windows XP???
