i am going to try this asap. If this works, you just saved me from buying another ps3, because one of my 4 ps3s laser went out, therefore, no 4 player zombie lan
update: ok I used the psn tekken game i had already installed on my jb ps3 that can boot from xmb. in dev_hdd0/game/NPEA00019
i replaced the USRDIR from the tekken game with the original cod waw USRDIR with the modified eboot that lets u launch from xmb. then Replaced tekken sfo with the sfo from the update 1.07pkg for world at war, which made a folder located //dev_hdd0/game/BLUS30192.
than I booted tekken from xmb and waw started playing. I notice that it doesnt have the 1.07 update applied because there was no nazi zombies on the main menu. so i tested the campain anad it worked great, i tried multiplayer but it freezes at a black screen, i tried system link but it keeps saying "downloading game settigns" at the bottom but i can still get back to the main menu.
so far only the campaign runs for me, again the update 1.07 did not apply itself
EDIt: I screwed up and accidently put red dead redemption sfo inside the tekken folder when it would of been the waw updated sfo lol. then i tried replacing the sfo with the updated one and now tekken doesnt show up on xmb. anyways i am now redueing everything from scratch
EDIT: i redid everything and same thing, only campaign and no 1.07 update was actually applied. btw using the original eboot from waw does not work. it will give u an error, i used a waw xmb pkg for 3.41 that i extracted the eboot out of to use so it can launch from xmb.
also i was bored and tried putting saw the game inside the tekken usdir and sfo but the game doesnt launch.
OK about the game hanging on 'downloading game settings' at coop system link menu when creating a game, i just tried deleting the 1.07 update from my non modded 3.55 ps3 and went to create a lan coop game and it also hangs at downloaing game setting.. ahh wtf
