Let's just say I hope you weren't counting on rumble or online play.
Computer and Video Games ran a follow-up interview to their previous question and answer session with Nintendo about the Virtual Console and uncovered some new information about the system.
The Nintendo 64 marked the first first-party inclusion of rumble technology in console video games. However, Virtual Console does not support rumble and so downloaded N64 games will not be able to use that feature.
Other than rumble support, Nintendo stressed that games running on the Virtual Console are "faithful recreations" of the originals with absolutely no alterations or enhancements. In particular, this means that there will be no fixes for games with slowdown, and multiplayer games cannot be played over the Internet.
Many people have wondered how buttons will be mapped considering the classic controller deviates from the design of the Nintendo 64 controller. Controller layout will be determined on a game-by-game basis and controller layouts will be detailed in the included electronic manual.
When asked whether GameCube controllers would continue to be manufactured and sold, Nintendo responded that no firm plans have been announced, but "GameCube accessories are still available from all good retailers."
Though they vary in size, the average size for NES downloads is 1MB, with 5MB for SNES games, and 32MB for N64 games. Each downloaded game receives its own channel on the Wii Channels screen and can be moved around to suit the user, but are not grouped by system.
Nintendo also stated that 2000 point Wii cards would be available for purchase online as well as in retailers. That statement along with previously released info implies that Wii points will initially only be available in blocks of 2000 no matter where they are purchased.
More Virtual Console games will be announced at a later date and begin release in 2007.
