pokeruby VS PokeExpansion

Pokémon Ruby/Sapphire, Pokémon FireRed/LeafGreen and Pokémon Emerald.

The Ruby/Sapphire disassembly on GitHub lists the parties and IVs: https://github.com/pret/pokeruby/blob/master/src/data/trainer_parties.h (use control + F). The IVs are given as numbers out of 255, so multiply by 31/255 and round down to get the actual IV. For example, if the IV is listed as 200, then the actual IV is floor(31 * 200 / 255) = 24. The disassembly also contains other information like items: https://github.com/pret/pokeruby/blob/master/src/data/trainers_en.h. Unnamed grunts are only identified by a number, but you can compare them with the parties of grunts listed on Bulbapedia.

You could always take a look at these decompilation projects on GitHub by Pret (it’s pretty interesting IMO!)

for instance you said "i'm already using that" but i think that's unlikely. is it possible you're using dizzyeggg's pokeexpansion? what i linked is rhh's pokeemerald-expansion. they are similarly named but not related at all. you shouldn't use PGE with rhh's expansion, and i don't think python is involved in the setup at all.

Sapphire is generally not used as ROM base. If you decide to use Emerald, you can use this instead: https://github.com/DizzyEggg/PokeExpansion.
