So I bought zombiu and it installed the title update for the game when i put the disk in. The issue is that the item duplication glitch was patched with that title update. (please dont give me your two cents on cheating and the ethics of doing it) You can delete the update from your system but it will not even let you play the game offline until you redownload the update. So apart from doing a full system format, is there any way to do this.
