Edition differences: original GBA and Nintendo Switch (2026)

Battle data describes Generation III rules. Availability notes distinguish native catches, evolution and breeding from original GBA imports. GBA games can trade with compatible Generation III games after the network quest; Switch supports local FireRed/LeafGreen trading and cannot import Pokémon from other games. Transfers to Pokémon HOME are one way.

GBA: AuroraTicket and MysticTicket required historical event distributions. Switch: both tickets are added after entering the Hall of Fame, providing access to Deoxys on Birth Island and Lugia/Ho-Oh on Navel Rock. Other event Pokémon and GBA imports are not made available by these tickets.

Original GBA: a roaming Entei or Raikou that successfully ends an encounter with Roar disappears permanently because of a game bug. The Switch editions fix this Roar disappearance bug.
