What I mean is, I ripped the game disc again to be sure that wasn't causing my issue. I also re-downloaded the EBOOT fix for 3.55 for Tiger Woods 2012. The EBOOT.BIN fixes are all over the net. There's even a ton in the EBOOT repository thread on here: http://www.ps3news.com/forums/ps3-ha...ry-117810.html
Not sure of COD4 is there, I didn't look. Install your game onto your PS3 with the method you normally use.
Put your new EBOOT.BIN that you downloaded onto a USB mem Stick or external HDD or whatever you preference is.
Use a file manager to navigate to HDD0/game/BLUSxxxxx<whatever COD4 is> /USRDIR. emove the EBOOT.BIN from here and replace it with the modified/fixed one you downloaded.
That's it. Launch game. I use Multiman and Gaia. Both work. If it's still not working I suspect it to be your "copy" of the game.
