this is what i did with my USA copy of GOW Ascension:
1. copy it to my external hard drive with Multiman
2. after copying I connected my external hard drive to my pc and rename the folder from _BCUS98232 to BCUS98232 (deleted the underscore)
3. I noticed multiman automatically splitted the big files to .66600, .66601, .66602 so I did NOT touch or replace anything
4. I went back to ps3 connect my external hard drive, launch multiman and press triangle on the game and select BD-Mirror and External, made sure there is a disc inside bluray
5. Go back to xmb and launch the game, but it goes back with an error.
I am on 4.30 Rogero v2.05, do I need to replace any files to make it work in external? Any help is greatly appreciated. Thank you.
