Wii Virtual Console Storage and Controller

 Games downloaded from Virtual Console library will be stored on Wii's built-in 512 MB flash memory, or on SD cards, though to play these games they must be copied back onto the Wii's internal memory. If the internal memory is filled, Virtual Console games can be deleted to create more room.

If the player wants to play those deleted games at a later date, they can be downloaded again at no additional cost. The Virtual Console games are locked to the Wii they were bought on, so a player cannot play their Virtual Console games on another Wii by simply swapping the memory cards. In the event that a Wii is damaged and the Virtual Console games can no longer be played, Nintendo will provide support.

The Virtual Console service is region-locked - that is, different versions of games are provided to different regions, and game availability may vary from region to region.

Virtual Console games can be played using three different controllers. The Wii Remote itself (turned on its side) can be used for NES, TurboGrafx-16, and some Sega Mega Drive/Genesis games, and the separately sold Nintendo "Classic Controller" can be used for all Virtual Console games. The controllers from the Nintendo GameCube can be used for all Nintendo systems' games, however Nintendo's site claims that it can only be used with some TurboGrafx-16 and Sega titles. All Virtual Console games have their buttons mapped to the respective buttons on the controllers, e.g. users cannot use X and Y instead of A and B.

With the release of Bomberman '93, it was revealed that TurboGrafx-16 games can support full 5 player games using a combination of Wii Remotes/Classic Controllers and GameCube Controllers (at least one controller has to be a Remote or Classic controller, and at least one has to be a GameCube Controller).
