>>48981863I'm aware of this catch 22 and haven't decided how to handle it. I don't have the skills to make a custom tileset and custom tiles tend to have different artstyles compared to Hoenn's tiles.
None of the other areas I'm adding have this issue.
>Vermillion City - Kanto-Path blocked by Snorlax
-Munchlax trade
-Diglet's Cave and part of route 2 explorable
-Lt. Surge battle
>Cianwood City - Johto-owner of Hoenn Safari zone sends player to scope out a location, but ultimately passes on the project
-Sacred Ash buyable from herbal shop here
-piece of Navel Rock map given to player for beating Chuck
>Snowpoint City - Sinnoh-Regigigas Totem Battle
-Candice battle
-Defog move tutor (clears hazards like new gens duh)
-Will probably need custom tiles for this
unfortunately
>Virbank City - Unova-Roxie Battle
-Virbank Complex hasn't been built yet, instead it's a wild area with unova pokemon you can't get in hoenn
>Ambrette Town - Kalos-Trade Hoenn fossils for other rare fossils at the museum
-Change Deoxys formes at the museum
-Feebas for Magikarp trade in under construction aquarium (only magikarp in the game)
>Konikoni City-First City outside of hoenn you visit
-Alolan Stones sold here
-Slaking for 6 IV Ditto trade here
-Heart Scale gift restaurant with each course being a battle ala X/Y
Vermillion might look odd in Emerald tiles given it's already in a gba game. and I do dislike kanto pandering, so it might end up getting cut for a Sevii island.
