Hello, today I've sold my NN3DS to get myself a 2DS. Ergonomically that device is very nice and the "nostalgia" Gameboy feeling comes up even more. My question is, to "install my backups" on the device, on what version should it max be? I remember (- 1 year ago) on my NN3DS it had to be at max 10.4 or 10.7, I don't know because above that nintendo patched that signature thing to install unsigned stuff. Did it change? Thanks truly for your help!
