Adding new Pokémon into Pokered disassembly?

Hi! I'm interested in creating a hack for Pokémon Red that adds in some beta Pokémon from the SpaceWorld '97 demo, but I don't really have a clue on how I would add new Pokémon in. I've looked all over for guides, but every one I've seen seems outdated compared to Pokered's current version. Is there a tutorial that someone can link me to?

I'm sorry you're being ignored. Their isn't any up to date tutorials on how to add new Pokemon into Pokered, I'd know. I even asked the guy in charge of the disassembly's Github page and they said they were working on one, though it has been almost a month and nothing has come of it yet.
