I think I read (can't find the post) that Duplex did it in one of their releases. Checking the difference of the .sdat in that release compared to the original one might show something. I have no knowledge of this though.
I know why there isn't a fix for MGS update 2.0 Its 500+MB of SELF files. There are about 75 files to patch. All are 4.00 firmware and for me scetool wont decrypt any of them.
Can someone else check this for me. I've already unlocked the DLC so it wont show up anymore.
It's probably a bit early to ask, but if someone could do a fix for Toki_to_Eien_Tokitowa_JPN_PS3-HR, I'd highly highly appreciate it. Thanks in advance, and thanks for this great thread!
