[Script] Swapping hero sprite in game- Fire Red

[Mxtrainer87]

Hey everyone,

I've reviewed script posts I'm wondering though in my situation I'm making a yellow gba hack im trying to have the ash sprite created for once the game starts to disappear and the new one show with pikachu on his hat either when Oak asks if you want to give pikachu a nickname or appear like the original game right after the Gary fight at professors Oaks lab (with a comment saying looks like pikachu dislikes the pokeball. I tried a few scripts nothing seems to work.

I know how to make regular msg scripts and legendary battles but this is different.

I would greatly appreciate some help

For knowledge: First Ash sprite is #1 in my owm and the one with pikachu on the hat is 233 since I thought about implementing this late. Originally had pikachu on the hat first when the game starts but want to push myself to the limit

I am new to these things but there is a YouTube video made by a channel called 'Aspiring PokeTrainer'
Title : In game character swap
It's better to search - in game character swap ROM hacking
Hope I helped

I think he knows how to do it, but he needs the character to change the overworld by setflags
