I am thinking of using a savegame exploit to mod my XBox for high definition only. Once I have done this, how does Enigmah work? Do you boot from it, select NTSC and from then on, everything stays in NTSC? Do I need to do all of the guoki tutorial or can I get away with just the first bit? Also, if I perform this mod, what are the risks and what other benefits will I get? Thanks a lot in advance.
