Before even considering asking for help on this subject, make sure you've tried the latest version of PCSX2 and configure your copy of PCSX2 using the guide at http://ps2iso.net/showthread.php?t=15441. Also, check the game is supported in http://pcsx2.net/compat.php
Afterwards, if you need help on PS2 emulation, you MUST post:

-Your computer specifications (cpu, graphics etc)
-The OS you are running (XP, Vista, Linux) etc
-Which version of pcsx2 you are running (latest is 0.9.5 beta, try that if you are running an older version before asking for help)
-Which plugins you are using (e.g. ZeroGS, Gsdx9, PEOPS SPU2 Plugin, ZeroFrog SPU2 plugin etc).
-The game you're trying to run AND it's region, e.g. PAL, NTSC etc.

This will save a lot of time from people asking about these details if they are given beforehand. Thanks.
