Looks like "TeamSGK" are just a couple of fakes, those "patches" aren't really theirs, in fact they got nothing to do with them. The Crysis 2 "patch" is really the 1.04 update for BLUS30632 (Crysis 2) and the "patch" for PS Move Heroes is just the 1.01 update for BCES00956 (PlayStation Move Heroes).
All they did is download the 3.50 firmware update (.PKG) file from a program like "PS3 Game Update Finder" and upload it and take credit it for it.
If I recall correctly these games were fixed when they were first released. They could have just put the fixed Eboot.bin file in a .PKG file, the only pro you have by doing this is that you can play games from the original disc without the need of backing up the game.
