Pokémon games on the GBA, including Pokémon Ruby, Sapphire, Emerald, FireRed, and LeafGreen, elevated the franchise with updated visuals, double battles, abilities, and natures. The Hoenn region introduced 135 new Pokémon and deeper strategic elements. These titles also brought wireless connectivity via the GBA Wireless Adapter, alongside improved in-game features like Pokémon Contests, secret bases, and the Battle Frontier in Emerald. The GBA era is remembered fondly for its innovation and replayability.
