I got the USUM legendary encounters working (soft reset bot) by using the Tapus (SM) mode (i do however use a thin piece of paper to keep the joystick moving upwards to start the encounter)...
I will update when i get a legit positive match with my filter (shiny).
Edit: Found my shiny...
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.
