Pokémon Golden Shield is a completed NDS ROM hack by cos_mino, built on Pokémon HeartGold. It reimagines the Johto region with a Pokédex centered on the Galar region from Sword & Shield, featuring Generation 8 wild encounters and updated trainer teams. The hack uses the hg-engine battle engine to bring moves, items, and abilities up to Generation 9, while preserving the original story structure through the post-game with script adjustments to fit the new roster.
