add me lets play sometime i dont do vc

Does anyone here know how to make custom splatfests? We could organize some, as we have pretty much active players here.

I'm having problems with copy and paste my save from my non-pretendo to pretendo user. Do I need to copy the 'common' too? When I do it, it says there's no 'common' save. I did it with splatoon no problem srry bad english
