Nope.
No.
Wii games, Gamecube games, and games from the Shop Channel either NES, SNES, N64, or WiiWare.
The SNES is a great system and so is the N64 i had a SNES before i loved it but now i have a N64 and i like it too personally its on you.
psp emulators, (or any type of emulator, N64 Snes etc.) allows you to play that type of system on you CPU with the games you download.
No. While it is technically possible, Nintendo (or anyone else for that matter) have not released an adapter to allow this. There is a new console out now called the FC Twin that has slots for both NES and SNES and can play both. Hope this helps.
No the game cartridges are different shapes. Nor does the N64 OS support SNes games.
Yes, but it's not easy to do so.
You can play them for free on a site called http://www.vizzed.com/vizzedboard/thread.php?id=14474&ref=84132 but it requires a plugin for SegaGenesis &n64/gba&snes
You will have to download an emulator. Once you are able to download this emulator, which can be for SNES, NES, N64, Atari, and many others, you will have to download roms. Roms are the games for the emulator. So if you download battle toads, you will have to open it with the emulator you downloaded.
Ds, DSI, NES, SNES, N64 and many more
No a PS2 will not play Nintendo 64 games
To play NES games on the Nintendo 64 you need a device called the TriStar 64. It allows you to play NES, SNES and N64 games on your Nintendo 64. It's a bit rare and pricey but you might find it on Amazon and/or eBay. If you do get the TriStar 64, you can get one of those nes cartridges with an SD card slot, load up all your nes roms, and play all your nes games on your N64. Works the same for SNES and N64 cartridges with SD slots.
