Pokémon Colosseum

Pokémon Colosseum (ポケモンコロシアム, Pokémon Koroshiamu) is a role-playing video game developed by Genius Sonority and published by Nintendo as part of the Pokémon series, released exclusively for the Nintendo GameCube. Unlike previous titles, the game does not feature random encounters with Pokémon, but the player can steal ("Snag") the Pokémon of other Pokémon Trainers. The game also features several battle modes for single-player and multiplayer gameplay. Pokémon Ruby, Sapphire, Emerald, FireRed, and LeafGreen can connect to this game through trading and Battle Mode.

Those that pre-ordered the game received the Pokémon Colosseum Bonus Disc.

GCN-GBA Connectivity
In stable releases of VBA-M, the GCN-GBA connectivity does not work properly, causing severe slow-downs to the point where both games timeout before an emulated connection can be established. Although unstable and barely functional for Pokémon Colosseum, the recommended releases of VBA-M to use the GCN-GBA emulated hook-up are the WXVBAM versions. You may need to import the battery save that matches the game running in VBA-M while the GBA BIOS is active for Dolphin to establish the link properly. The save type for the compatible GBA Pokémon games are Flash 128K if automatic save detection does not work.

GBA Controller
If a GBA is selected for any of the ports except port 1 before the game is started, the emulator will ignore port 1 GameCube controller inputs. To fix, just set the ports to None before starting the game. It can be re-enabled once the game prompts you to if the user decides to try the GCN-GBA hook-up features without any ignored inputs.

Crash on the MAC OS X Build
After visiting Mt. Battle for the first time, entering a trainer battle will cause a crash just before the opposing trainer's Pokémon are loaded.

PAL Crashes
When playing the Arena mode in the PAL version, a crash can occur when attempting to register the Pokémon from Story mode to play later in the Colosseum mode.
