About Pokemon Ambrosia
Wandering overworld Pokémon, two level caps, and a war between Kanto and Hoenn make Pokémon Ambrosia a very different Crystal experience. DrUltimaMan's completed English GBC hack is the final version and places Johto between the opposing sides. Its open world is balanced by separate caps for training and catching, with rematches for every trainer and Gym Leader, updated battle AI, changing weather, and a rewritten Pokédex featuring Pokémon from the first six generations. Three recurring rivals include one that mirrors your team exactly. Post-game content adds optional bosses, new maps, Legendary Pokémon, Battle Frontier modes, and warping key items.
