PS2 virtual memory card signing
PS2 virtual memory card signing –
I am looking to modify some ps2 save games that are stored on the ps3's virtual ps2 memory card. When I examine the file structure it looks like the ps2 save game is encapsulated by a header and most likely a signed hash of the file. If I modify the save game it will not load on the ps3. Does anyone know if I can use the ps3 master key to sign the save games? Or has anyone been able to modify the ps2 save games for ps3?
I don't have a ps2 but I have ps2 games that I play on the ps3. I know that the ps2 games are hashed at the bottom (i think with with crc256 or something like that).
