[Question] Make two specific NPCs; One event, one is a shop. (Pokémon FR/LG RomHack)

[CarneMorta]

Hello everyone! I am working on a rather simple Romhack using Hex Maniac Advance and AdvanceMap Editor. It's going good so far, but in order to add two of the major features I wanted to implement, I have no clue where to begin, as I have zero coding experience with either engine.

I wanted to give the player the choice between a Pikachu and an Eevee AFTER the inital rival battle after you pick your starter. I want it to be like, one of the scientist guys walking up to you. I am not sure how complex of a script that would be, but any help is very appreciated.

The other one is simpler, I think. I wanted to add two/three evolutionary stones sellers around the region, so they aren't as scarce anymore, but still expensive to gather. How do I make such thing?

For the evolution stones, you can copy the PokeMart script and replace the texts in there.

As for the second starter, the way I did it was after a map transfer (leaving the PokeMart) with a switch turned on (received specific item) (you can create your own). The event that gives a second starter was on auto run, so it would automatically do it's thing and disappear after the event ends. Pretty similar to the initial starter giveaway.
