playstation 2 emulator

Can someone tell me how i can configure my ps2 emulator to run better? I just acquired a bunch of roms and they have some problems. Grandia II and Final fantasy XII break and phantasy star universal just shows a white screen but responds with sound when i touch the controller. i'm using pcsx2 0.9.6 and a quadcore with nvidia graphics card. Or is the problem just with those roms? Thanks...

Try diffrent graphic pluginshttp://forums.pcsx2.net/Forum-Plugins--72The emulator is not yet fully compatable with some roms, they may need a patch for the rom thats built into the emulatorAre , PCSX2 0.9.7 betahttp://forums.pcsx2.net/Forum-Public-beta-buildsPlugins update http://forums.pcsx2.net/Thread-Windows-Plugin-update-pack-August-2010
