"ninjhax"? if so, you can just scan a new QR code. https://smealum.github.io/ninjhax2/#qrcodeBy the way, Ninjhax was working just fine (on FirmWare 10.3.0-28U) before I updated to the most recent (FW 10.4.0-29U)... Is it possible that the exploit has been patched out only on my 3DS alone? Any help would be GREATLY appreciated!
