(adsbygoogle = window.adsbygoogle || []).push({}); I used the Duplex 3.55 fix and replaced the eboot, sfo, self files and the trophy file. But it won't play. Also why do I have to replace the trophy file?

I have never had to replace trophies but you want to make sure you don't have the original patch on there from b.o2. you need to duplex one. Personally it was a pain to do all these duplex patches so I upgraded to 4.30 cfw rogero and have had no problems. You should try it. But do not play online on black ops 2 on 3.55 or 4.30 because you WILL get banned.

Yeah inside the Fix folder was a troph file so i replaced that also. I'm thinking about upgrading also, but i'll finish the games that work on 3.55 before getting any new ones and upgrade
