It works, but you must have a Jtagged Xbox 360 Console to run XeX Menu. Retails won’t work
This tut is also useful for if your shipping a Jtag to someone, you can include XeX menu on a disk, so they don’t have to go through all the trouble of downloading it through the computer, etc.
Old topic i know but i want to state a big fact here, when you stressed that “You MUST have a dual layered disc” that is false, a regular DVD -R will work just fine.
