I've been trying all night and it seems impossible to hit the right seed. I'm trying to get 2082 but I keep getting 2084, 2088, 2090. Do you usually press A at the last beep? I'm trying to get the event shiny entei on Platinum.
Do WNPCs change the coin flip?
EDIT: also, when I tried doing this on Azelf in Platinum as practice, I copied the seed from the time finder to the main RNG window, but I can't find the frame with the perfect IVs... Is there some trick to this?
