Much of the region’s northern areas are dominated by snow-covered mountains. Many of the region’s towns and cities have Pokémon Gyms designed to look like football stadiums, displaying both Dynamaxing and Gigantamaxing, as implemented by Rose, the Galar Pokémon League Chairman. The region’s center is populated by an Industrial Revolution-style city with steampunk elements.

To the south of the Galar region are countryside towns with cottages and Victorian architecture. The region itself is influenced by Great Britain, with many landmarks resembling the Houses of Parliament and the Cerne Abbas Giant. Shigeru Ohmori, the game’s director, described it as a more modern setting. The events of Sword and Shield take place in the Galar region, a large, narrow expanse of land that is one of many in the Pokémon world. to Gigantamax/Dynamax your pokemon (the ones that can Gigantamax/Dynamax) you need to get a wishing star and activate it in battle by pressing start. (creator’s commentary) this is my first rom so don’t expect anything to go head-to-head with these ROMs that have been in production for years.

Logically it is not 100% the same as the switch version but, it is as good as you’re gonna get for GBA. Also, be sure to check out Pokemon Sword and Shield Ultimate
