I'm not sure if this is the place to ask this, but 2+ hours of Google searches have returned no results for me. I received two store demo 3DS XL systems today. I was told that they are non-working, but they didn't come with "charge" cables. From what I've read, the store demo units are different from standard retail units as they have to be plugged in to work and that they don't not use battery power at all. The problem I have is that I didn't receive any power adapters with these and they have a strange power port instead of the standard one. Even the tabs for a dock are absent. This port does not accept a DS/DS Lite/DSi tip. I don't have a Advance Micro charger, but I believe that tip was wider than this port. The port is not a USB Micro B either as the jack to those is a little wider than the port on these. I've attached a couple photos of the charge (power) port and one of the SD card slot. Both units that I received are Blue, but both have a gray SD port cover. Any information would be appreciated.
