In case of someone is having the same issue that i was, if you play Splatoon on Cemu, and get disconnected mid-game, check the firewall or the antivirus and add an exception to Cemu.

stage rotation isn't working?

anyone knows why my game keep disconnecting mid-game and how can i fix it?

Anyone knows how to fix splatoon disconnecting mid-game?
