I just wanted to post this and get some suggestions going. So I wanted to fix one of my spare 3dsxls so I bought a broken one from that would Frankenstein with my one. The one I bought claimed that it could not read gamecards and that the sd card slot was broken. What I got was very different. After Googling I discovered that the hardware I had was a customized 3ds designed as a tour guide for the Louvre. It behaves alot different than a normal 3ds, it appears to have a custom boot card that runs the os, the os is dependent on software contained on the sd card. The 3ds does not appear to have a nintendo 3ds os. It cannot boot games. This was something truly interesting, so what do you guys suggest we do? From all appearances it doesnt seem secure, and could help in the development of a truly independent firmware. So Where do we start. Heres a video of the 3ds in action.
