Sounds like the data in that folder is corrupted or sth... can't imagine why else it would do that. Do you have important saves on it? Or is it not worth trying to recover it?
Not sure about smash bros either. I play on my NA legit cart all the time soo..
ok something happened o_o
I've made what I told you: just formated the 3DS' SD , placed the files backup again, the all stuff appeared there on sysnand
then I boot the exploit : it enter direct on the menu(with the digtal content there) it was strange because I formated it, right? I didn't made a backyp of the emunand o-o
Then entered the system configuration to make sure it not simples reseted to the sysnand menu, but there was : GW3D 9.4.0-21U
This mean that this still the emunand, right? o_o but how? e3e
Should I format emunand again and see what happens?
Edit :
Ok I tried it : formated emunand on GW and got it like was : placing the folders on the SD does not show the digital content on sysnand and emunand, it could be updated and stuffs (strange that the miiplaza are asking for update, not sure if I should do that o-o).
So I think the way to have my content there is formating this SD/deleting the files here and placing the folders again ....
But it still be the normal emunand? e3e
