These Game Boy Advance titles originally released in September 2004 in this region, and were remakes of the original Pokémon titles on Game Boy. These newer releases were also compatible with the Game Boy Advance Wireless Adapter, allowing players to connect up without cables.
Of course, the mere mention of this has already led to a bunch of requests - with many fans calling for these games to return via Nintendo's Switch Online subscription service. Although there are already some Pokémon games on this retro service, we're yet to see a mainline release.
The most recent Pokémon title to join the service was Pokémon Mystery Dungeon: Red Rescue Team, which was made available on the GBA service last month. This latest anniversary celebration of FireRed and LeafGreen follows the Japanese one earlier this year in January.
