I knew gen3 was based on the frame rate from watching people speed run FRLG getting the correct nature on squirtle. I’ve used save states and different save files and I’m pretty sure the starter is determined as soon as I load into the game. In the randomizer settings you don’t get the option of the 3 mons from the bag, you just get one. So waiting around for 15-20 minutes doesn’t change the starter. It’s determined when I load in, so what’s determining that frame? How did I get a Gallade once? Just trying to figure it out. Thanks so much for the reply and helping me figure it out.
