[pokefirered] how to change rival starter

[tinferbrains]

Thanks to a previous post I was able to randomize the starter options offered to the player, but the rival still gets the traditional starter strong against the type you chose. How would I go about changing the Pokemon your rival ends up with? I imagine I'll probably have to change the team for each rival battle, but correct me if I'm wrong.

how to change rival starter

It doesn't look like you made an effort to read Oak's Lab's scripts.inc file, huh.
Just like there's a temporary variable that is used to store the Player's starter before giving it to them (VAR_TEMP_2 which uses PLAYER_STARTER_SPECIES as a local label), there's a variable used to control the Rival's, VAR_TEMP_3 via the local label RIVAL_STARTER_SPECIES. Like I said in the other thread, both of these are located near the top of the scripts.inc file.
You're gonna have to modify its value in a similar way than you modified the value of VAR_TEMP_2/PLAYER_STARTER_SPECIES.

I imagine I'll probably have to change the team for each rival battle, but correct me if I'm wrong.

You're correct, yes. Each rival battle uses a separate opponent ID with their own parties. All the relevant data is in src/data/trainers.h and src/data/trainer_parties.h.

Sorry, I should have remembered to read the temp variables in the script file. Duly noted. Also, thanks for the location of the party data and confirming my suspicion
