Clean it, or put it in the other way.

You put the game in where you would put a wii game.
All Wii's have WiFi
You would have to put in newBatteries. if that does not work, try taking it to gamestop. there could be something wrong with the remote.
you put a game into the wii and you play it
No, If you do your computer will not read it. Same thing if you put a disk for a computer in the Wii.
To put a Wii game in make sure the picture faces right.
You don't, unless you buy it from a download site, put it on an sd card, and put it in your Wii, which is not worth it. it probably will cost you more, and could mess up your wii. Just get the Wii points, or play it on a NES (the system that it was originally made for) Another idea I thought of, is to find a friend who has it, put it on a sd card (go to Options from the Wii menu and go to system memory), copy it onto a computer hard drive with an SD card reader, put the game back on your friend's wii, copy it onto a card from the computer, and then put it on your wii (not sure if this will work. I might test it sometime) You can also play any NES game on http://nintendo8.com/all/
