I'v been having a hard time to get this to work on my external drive. I followed the PSARC tutorial and copied the pak22 folder to PS3_GAME\USRDIR\build\main were the .psarc file were located.
The game starts with no problem from external, disc-less but in the first chapter with the train, i can't seem to view the textures. It's just a floating train in the middle of nowhere, can't jump to the edge, he just dies. Does anyone have an solution for this?
