I modded my switch and mine is unpatched erista.
I'm using emummc only so I'm not get banned.
My hos and emummc is both 18.0.0 firmware version.
When I play some games which has leaderboards(like watermelon game) error code 2123-0011 pops up.
But if I press OK then I can still continue the game...
Only thing drive me crazy is all these new horror games nowadays is its so dark, all time. I can't even play them. I understand they trying to create spooky but be creative a little, not just darkness with pop out scare scenes.
