Eboot can directly install the PKG patch. 2. 1, or 2.0 plus 2.0B dual boot can be used. But that's not the problem. The problem is that there is no patch for 1.03 in the traditional Chinese version. Then upgrade, instead of trying to find a patch, plug in the PS3 network cable, prompt the upgrade, complete the upgrade, re-enter the game, and it's over. Because E3 and PKG are in tune, especially the official PKG. If you want to download it yourself, E3 version 2. 1, download an E3 PKG installation, enter E3 PKG installation, select the PKG you want to use, press any key to exit after downloading, but don't use PS key. Also, don't repackage ISO by downloading DLC. There are many DLC like GTA5 or flash tracks described, so repackaging is too troublesome.
