[Gen 3][Decomp] How to start with romhacking with decomp in 2026?

Hi I always wanted to create a rom hack, and I know I could do either binary hacking or decomp. I have no idea how to start though. I'd like to do decomp, but:

  1. How much free space is left to poke emerald, now that pokemon expansion has up to 9 gen pokemon and items ?

  2. Is improving the graphics (changing tiles) still super boring and time consuming ?

  3. Is there a way to import only till 5-6° gen ? (I don't like newer pokemon)

  4. Is there a guide I can follow to start decomp, from installation to setting things up ?

  5. Any advice ?

Thank you. Would be great to talk with someone experienced with this, at least to overcome the entry barrier. I prefer decomp because I used to binary hack many years ago, but at some point I messed up and ruined everything (probably a conflict between the tools).
