No, it will not be, because it will use cartridges rather than discs. However, there is hope that there will be digital content available through the console, so that we can still play older games. You won't be able to play Wii or Wii U games directly and it's still not confirmed if certain games will have backwards compatibility if bought digitally.
yes its backward compatible with the ds and dsi games.
no
No there not.
Yes, the 3DS are backwards compatible.
Depends what you mean by 'cord' - if you mean the power supply or controllers, then very definitely no. The Audio/Video hookups, however, are backwards-compatible with the Super NES, and also FORWARD-compatible with the Nintendo GameCube.
The answer is no the gamecube controller will not work on the nintendo 64 it only works for the gamecube and the newer wii system.
no but if you have a gameboy colour you can play Mario bros on that
The function and technology should be better, yes, but it won't be backwards compatible with any of the other consoles.
No the game cartridges are different shapes. Nor does the N64 OS support SNes games.
Backwards compatible on 360!
Yes, the 3DS will be backwards compatible with the DS, but the standard DS games will not be in 3D.
No, the Nintendo Wii cannot play Wii U games
Nintendo 64
