What RBY, GSC, RSE, FRLG, DPPt, HGSS, BW, B2W2, XY, ORAS, SM, USUM, LGPE, SwSh, BDSP, PLA, SV and PLZA stand for — every mainline Pokémon game abbreviation and the games it stands for, plus the short code PokéMaps uses in its own map addresses.
DPPt (also DPP) — Pokémon Diamond, Pearl and Platinum. Pokémon Diamond, Pearl & Platinum interactive map (Sinnoh). PokéMaps URL code: dpp. We use the shorter dpp: the trailing t in DPPt is a Bulbapedia convention rather than how the games are spoken about.
BW — Pokémon Black and White. Unova. PokéMaps URL code: bw.
B2W2 — Pokémon Black 2 and White 2. Unova. PokéMaps URL code: b2w2. Kept separate from bw even though both are Unova: Black 2 and White 2 genuinely changed the map — Aspertia, Floccesy and Virbank were added in the west, Route 10, Cold Storage and Black City / White Forest are gone.
Generation 6
XY — Pokémon X and Y. Kalos. PokéMaps URL code: xy.
ORAS (also ΩRαS) — Pokémon Omega Ruby and Alpha Sapphire. Hoenn. PokéMaps URL code: oras.
Generation 7
SM — Pokémon Sun and Moon. Alola. PokéMaps URL code: sm.
USUM — Pokémon Ultra Sun and Ultra Moon. Alola. PokéMaps URL code: sm. Folded into sm: Ultra Sun and Ultra Moon share Alola’s geography with Sun and Moon — same islands, same routes — so one map serves all four, with version notes for what the Ultra games add.
LGPE — Pokémon Let's Go, Pikachu! and Let's Go, Eevee!. Kanto. PokéMaps URL code: lgpe.
Generation 8
SwSh — Pokémon Sword and Shield. Galar. PokéMaps URL code: swsh.
BDSP — Pokémon Brilliant Diamond and Shining Pearl. Sinnoh. PokéMaps URL code: bdsp.
PLA — Pokémon Legends: Arceus. Pokémon Legends: Arceus interactive map (Hisui). PokéMaps URL code: la. We drop the P: l stands for Legends throughout our addresses, so Legends: Arceus is la and Legends: Z-A is lza. Better: LA — the P for Pokémon is redundant.
PLZA — Pokémon Legends: Z-A. Pokémon Legends: Z-A interactive map (Lumiose City). PokéMaps URL code: lza. Same rule as PLA: l is Legends, so Legends: Z-A is lza. Better: LZA — the P for Pokémon is redundant.
