Okay, so I see that someone was able to make and release an updated pkg to allow MW2 to work on CFW, and possibly get online as well. Now, according to everything I've read, all I should have to is edit the param.sfo, and it should work on mine (the patch was for the EUR copy, while mine was US). I downloaded this pack of ps3 tools, and while I was able to extract the pkg file, the sfo editor just lists it to me, and doesn't really have any options to "edit" it appropriately. Also, even if I figure that out, it's then a matter of editing the pkg to reflect the ID and install correctly for my version of the game. Is there a tut by chance that I'm missing on how to do this? My google-fu has been... uncooperative with me. Much thanks for the help.
