I recently acquired a r4i gold 3ds cart and have been struggling to get it to work for me with little luck in the endeavor. I got it updated so the game that comes up is dorasu and it claims to be compatible with NDSi 1.4.5 and 3DS 6.2.0-12. However it does not work with my 3DS that has is currently up to date and is on version 8.1.0-19U. What I am wondering is if their is an update that I am missing that will allow compatibility between my card and 3DS or, if I dropped money into a worthless pit that may never work for my system. Any help would be fantastic, I will try what people recommend!
