I really want to replay my copy of White 2, but I have the Meloetta skin on my C-gear which I absolutely adore and dont want to lose. Is there any way I can preserve it now that DS internet compatibilty is dead? Like maybe trade it to my copy of Black 2? Black 2 is where all my Gen V Pokes are if you're wondering why I don't just restart that version. 100+ trades would be a very long and preferably avoidable solution.
To my knowledge, no, there is not a way to preserve your C-Gear skin after restarting your game, as Global Link for Gen V was closed and that's how you got the C-Gear skins.
Hope I helped!
