You talkin to me?
(adsbygoogle = window.adsbygoogle || []).push({}); The main problem I have had with patch_mp.ff files is that when it came to copying the gscblock back into the patch_mp.ff file, the block was always bigger than the original.

So I had a brainwave of instead to compressing back into the encrypted GSC block, I just compressed the unencrypted GSC block straignt back into the patch_mp.ff file at offset 0x0000B4A0.

    packzip.exe -o 0x0000B4A0 -w -15 <decryptedgsc.dat> <patch_mp.ff>


The old and new patch_mp.ff files are exactly the same size! Don't know whether or not this will work, but here it is!

Recompiling this son of a bitch is a pain in the ass.
U gotta get the 0x000002 into the "modified.dat" into the 0x0000027 and the back into the patch, witch then has to be recompiled.

You need to extract the blocks first with offzip, modify them and then "inject" them back with packzip. If you don't get any blocks with offzip then it simply can't be done.
