I am messing about in my spare time with the 105 patch for SOCOM 4. I've managed to get the eboot, self and sprx fixed now (although i did it by converting the self and sprx to retail, but that is another story).
Unfortunately the update also contains an .sdat file (tpps.sparc.sdat). I've just started doing some research on this file. Seems it is an psarc archive that is signed with a static key. Anyone have info on decrypting/encrypting it?
Without modifying the .sdat or its contents there is still a version check not fixed. I'm pretty sure it is in the .sdat file. To test I replaced the .sdat with one from an earlier 3.50 patch v1.01 and it viola worked! Version check gone.
I'm certain there are other patches out there that have .sdats so any info would be a big help. Thanks
i made this too, the game starts but in the first mission the game freeze
