Regional Forms

Polished has been implementing Regional Forms (RFs), and that's WIP as of Jun. 2021.

Form Data

The form table (variant_forms.asm, major spoilers there!) has two sections: CosmeticSpeciesAndFormTable and VariantSpeciesAndFormTable.

Polished has some exclusive tweaks: e.g. the Red Gyarados is now a new form of Gyarados rather than the Shiny variant. (This leads to no Shiny animations or icons for that and to a possible "Shiny Red Gyarados", who is also red.)

Note also:

• Some of the RFs have their animations undefined, i.e. their anim0 and anim1 in the GFX directory being empty. See the directory for details. (gfx/pokemon)
• The signature moves and Abilities don't necessarily come along due to technical limitations.

Availability

Wild Encounters

• Alolan Rattata & Raticate
• Alolan Sandshrew & Sandslash
• Alolan Vulpix & Ninetales
• Alolan Graveler (therefore Geodude via breeding, Golem via evolution)
• Alolan Diglett & Dugtrio

The wild encounter tables define which form to appear. (data/wild) An area may give more than one forms of the same species in this way, e.g. both Kantonian and Alolan Graveler in Rock Tunnel.

The Ice Stone is available for those icy species.

Evolutions

• Alolan Raichu
• Alolan Exeggutor
• Alolan Marowak

Polished has added an evolution item named "Odd Souvenir" for those branched evolutions, which comes in the post-game. The item looks much like the Strange Souvenir from Alola.

Note: The game currently gives only one copy of Odd Souvenirs.

Data-wise

• Alolan Meowth & Persian
• Galarian Ponyta & Rapidash
• Galarian Slowpoke, Slowbro & Slowking
• Alolan Grimer & Muk
• Galarian Weezing
• Galarian Articuno, Zapdos & Moltres

These species have been implemented but haven't got their encounters/gifts defined yet. This means that your opponents may have them and that you can grind Wonder Trades for getting the non-Legendaries of them. or cheat for them :P

No Data

• Galarian Meowth
• Galarian Farfetch'd
• Galarian Mr. Mime
• Galarian Corsola

They're absent at the moment as the game has no rooms for their evolutions. It'll need another major update.

Trivia

• Before the wild encounter mechanics sets forms individually, the core engine used to set area-specific forms. (the diff: e1336d94).
