So my sister bought an R4 recently and wanted my help. Unfortunately, I haven't got a clue as I haven't used one in years. I have a sneaky feeling that the one my sister purchased is a fake one. Anyway, I tried to put a firmware in there but I get an error saying it can't access _dsmenu.dat. http://imgur.com/7iuscJI http://imgur.com/fuVWavl This is where I'm supposed to be downloading the firmware from: http://www.r4carduk.com/ Any help is appreciated.
