My friend has an 4.5 O3DS which I plan to update to 9.2 via sysupdater and then install Luma3DS.
Will his ds savegames, in particular his Pokemon Black savegame, remain after doing all this?
If not, is there a way to backup and restore his savegames using only a 3DS?
I'm seeing a bunch of people trying to sell consoles for way more than what they are actually worth (regardless of the overall conditions) just because of the fucking motherboard revision
