It is an original back up of Gta IV(never updated), I mod the common and ps3 rpfs. I use this as my backup in case the mods do not work. It also contains GTA IV pngs and cdimage files.
No, firmware above 3.55 is all legit, which means no game backups run internal or external(no mods will work). One could play the way Sony wants you to play with any FW above 3.55. Sorry man, Hopefully some CFW will be released soon for all who updated.
kk ty broskiey. i wasn't thinking so much as a backup but more as a hotswap method where the moded data is saved 2 the hdd and will run the mods that way
