Here we have a mod for the DC that will allow you to change the region and video output of the console. All it requires is soldering one wire, bridging two points (if needed) and burning the Region Changer to CD.
Instructions and info
Region Changer v1.5
Saves me having to use DC-X every time I want to play a game; I can just change the DC to Japanese mode and directly boot Trigger Heart or Guilty Gear.
