To all those that say undead nightmare works are you saying that because the main game works?? The undead nightmare portion still requires psn to sign in.
I posted how to get the original game working when it first came out but the zombie portion surely still does the same thing and asks you to sign into the PSN to activate the dlc packs.
I installed the eboot.bin and rdr2.self from riku, yeah the main game works (like it always had since I posted the fix for it) but the zombie portion still asks for PSN sign in.
Are you removing the lan from the ps3 to get it to work or what??
