Xbox:Enigmah-X

Enigmah-X is an application that switches your EEPROM region to either PAL or NTSC. This is useful because using NTSC region allows your Xbox to output at 480p, 720p and 1080i through component cables.

Changing your Region
Run the application and it will display your current region. Press A to change it to PAL, and press B to change it to NTSC. To exit, press LT+RT+Black.
