(adsbygoogle = window.adsbygoogle || []).push({}); Hi im Doggyshizz this is incomplete hoping it will point some in the right direction as i have only have my CFW now since my laser on my retail burned out here we go what you have to do
rename a gsc to this buttons_default.cfg
clear it out put these in it

/Dvars & Test
xblive_loggedin 1
xblive_playEvenIfDown 1
masterPort 20810
masterServerName cod4master.activision.com
matchmaking_debug 1
session_immediateDeleteTinySessions 0
session_nonblocking 1
playlist 1
playlistFilename playlists.info
privateMatch_joinPassword ""
privateMatch_serverPassword ""

now using hex editor open up your patch-extract.dat
and find this "systemlink" 0 put value to 1

save and put patch on ps3

i tested & the farthest i could go with this was just to the party menu

Yes i know thats why its incomplete there isn't alot of releases anymore but I know Uk_viper knows it and I think the fallen knows how to get online without signing in
