(adsbygoogle = window.adsbygoogle || []).push({}); i really need help,

basically I downloaded Tony Hawk American Wasteland as a PS2 iSO to play on my CFW PS3, downloaded perfectly fine, no problems with the file until i put it on my PS3, sometimes when i load the game the loading screen will flash then my screen will go black, other times it actually loads up fine but some textures are missing, at the main menu the floor doesn't show up, when i try to play free play i can't see the skaters etc, anyway after i get passed all this BS and get into the game i can skate around, ride BMX all that stuff, but the floor and some other things just glitches out, flashes black, freezes, sometimes even freezes my console, nothing wrong with my PS3 because i've tested Crash of the Titans iSO to see if that had the same problem but it worked flawlessly, any ideas what it could be? i've downloaded THAW iSO from 4 different sites and it gives the same outcome everytime.

firmware: 4,78.1 DRex

REBUG Tool Box settings:
webMAN enabled
PS2 Emulator, COBRA
COBRA Mode Enabled
Debug Menu Type, obviously DEX

in theory it should work because the settings are fine and all that stuff, maybe its just the iSO's? i've seen a few other people with THAW on their PS3s and they dont have this problem, any help is much appreciated

I beleive it is just the iso, since the other one is working fine :/

could you point me in the right direction of downloading the correct iSO that will work? i've downloaded 4 as i said in the thread but none seem to work and no one else i know is having this problem.
