Okay so I bought a lot of 37 3DS systems for just 475 Bucks as they all needed fixing ( asd I love to have that as a hobby ) but I soon noticed after 5 systems that they were all Kiosk Units and got a bit of a fight with the guy who sold them to me as he meant that he bought them off a guy on a fleemarket in April and I tryed to expain to him that they were probably ones used in stores and just were destroyed after they were used ( Just toren the upper screen off ) and well there were 5 3ds ones and 32 3ds xl ones and well the xl ones nothing special but the original little ones all blue but of 1 of them well then it didnt looked the same way a the others and wanting to get ready to send them back to the seller as I noticed a little thing that there backpannel has been WAY different and expectet it just to be a Japanese version of the 3ds but then saw the date of 2010 ... I pulled the Motherboard out and put it into another system and well there was a broken screnn so I just expectet that somebody f up while installing a coustom firmware ( As I somestimes get there systems ) almost wanting to throw it into the defictive pile as I thought it strange that the background color wasnt blue but black so I put it into another system ( On of mine ) and there it was a DEV MENU and well going though this stuff trying not to screw something up I was very cautius and found a unnamed title called "3D Challange" and I cant find anything to this name on the web / I dont think this game has been dumped yet does anbody have any idea what it is / or if somebody has heard about it allready
