Alright, cool. They still have it at my local Best Buy store.
Check that out, I should have explained it pretty well in the video... I would really love to know what that is!
Wait you are the guy who uploaded the video ? I think I got such a 3DS main board it doesnt have the normal Charging port there its some kind of HDMI connector that is probably used to send power and data to the 3ds but I sadly cant do anything with the Board without it beeing pluged in
