Final Technical Note for 3.55 Users: If you experience the infamous “black screen after the intro videos,” your PKG may be missing a critical PS3_GAME/USRDIR/ structure. In that case, extract the PKG using pkgview on PC, verify the EBOOT.BIN is signed for 3.55, and rebuild it. Or, simply upgrade to a modern CFW like Evilnat 4.90, which maintains full 3.55 PKG compatibility while adding better stability. Happy fighting Ufc Undisputed 3 Ps3 3.55 Pkg
