Disable Pokémon animation on Birch's intro Pokémon - pret/pokeemerald GitHub Wiki
If, for consistency's sake, you also want to disable the animation on Prof. Birch's intro Pokémon, luckily this one couldn't be easier.
Just open up src/main_menu.c
and go to the function Task_NewGameBirchSpeechSub_WaitForLotad
.
Then change if (sprite->callback != SpriteCallbackDummy)
to if (sprite->callback == SpriteCallbackDummy)
!
If you missed that, you're literally just changing !=
to ==
.
