Amro, only you need to check it out.
If the game contains SPRX files, and there are no such files in the PSN patch - this game will not work on OFW!!!.
That is, the SPRX files must be officially signed by the NPDRM signature, which must be taken from the PSN Update patch and replaced.

In PSN update patch always all files are signed NPDRM to start from the hard drive PS3.
The blue-ray disk files do not have a NPDRM signature, so such files will not work on OFW (on CFW work). If they do not have a substitute.
For example, in some games there is a file NTJOBCODE.PPU.SPRX, replacement of which has not yet occurred in PSN Update Patches.
