Controllers can be changed at the Multiplayer booth in the Terminal area after finishing the first stage.

Passwords have been found in Nintendo Power magazines, the official game website, or online.

The game was originally planned to also have Pokémon from Gold and Silver and Ruby and Sapphire, but they were not implemented presumably due to WiiWare's 40 megabytes size limit.

This gets proven further when it was discovered that the games collection booth was hard coded to not show Pokémon 152 through 388, and Arceus.

Once a Pokémon is recruited with Power Points of 100 or more (or they lose all their lives twice) a short video is displayed in which the Battle Royale doors open and then a screenshot appears stating that the demo is over.
