Editing a PS2 CD

Is it possible to hex edit the files directly on a bf2 disc?Or replace the files?

To the best of my knowledge it is impossible to edit the original PlayStation disc. People have copied the contents to a PC, made edits and then burned a new disk. In effect this is a bootleg disk and I believe the keyhash needs to be modified in order to play it on line. In order for others to play the same mods they would need a similar counterfeit disk. I have not tried any of this myself, not just because of the legal implications but If I’m going to do all that work, why not use the PC version instead? It’s easier, gives much better results and it’s legal.

Best way I know is having a phat modded PS2 with a hard drive in there, then create an ISO of SWBF2. Find some programs that let you edit that ISO, then you should be able to run it off your modded PS2's hard drive, or burn it to a disk and run it.

The bad part is it basically all requires a modded PS2. Eh... unless you feel like doing that time-consuming swap-out thing.

Anyway, listen to Pyro. He knows his stuff lol
