Suggestion:
u downloaded a wii game
if u mean u donwloaded a wii game on the internet using uttorent then u have to download a unrar programme such as winrar or supernzb
I reccomand nzb because it is free.So to unrar it u then open nzb nd click rar then click select rar file nd select the game file and wait untill its extracted.When its extracted it will be in in the same file as the game but it will be called unextracted files or if the game has more files then 1 then click on the game file and it will be there called unextracted files.
After extracting u need to burn it.Many people use imgburn but i use nero 8 ur computer should have it if not then u can download it type nero 8 on google.so after extracting double click on the iso file of the game nd it should come up with a thing that will say pick a programme to open with nd pick nero 8 nd from there jus click next and burn nd then jus wait for about 8 mins nd then when its done the disc will come out nd u have downloaded it.
Occasionly supernzb will not be able to extract the file and at the bottom it will say archive damaged or corrupt there will still be a extracted file but just delete that because its not right nd look for a diffrent torrent
if u mean u have downloaded the wii classic games from the wii shop then u need the classic controller nd the game will be on the wii menu

don't listen to that enrique guy. he's not that informed. he is right, it is against the law though. everyone does it though. the only people who don't either have money they don't care to spend, don't know how or are a true hardcore gamer that believes in supporting the games with their funds. that said, i'll help ya. you need it hacked/soft modded. if you have that and it's newer wii, you'll probably want to use a usb loader, unless you have a hard modded system. the newer drives are not burnt disk friendly. 1st of all do not update if you are not on menu 4.3. it can be hacked but it's not as easily done. go to wiihacks.com. they do not support piracy there in any way shape or form. so don't even hint it. if you are one 4.2 it's a matter more or less of deleting a stubbed ios 249 and reinstalling one that allows you to work with the wii. 3.1-4.1 i believe you will need to just install the ios you need and 4.3 i've neve fooled with but i know there's a hack tutorial on wiihacks. goodluck and if you do download a game make sure you own the game you are downloading first to avoid any legal issues and jerks calling you names like dirty thief ect…
Funny Enrique! just go to the wii menu and play it from there.If you can't see it, it could be on the next page or on a memory card
Call the cops and tell them what you did. Dirty Criminal.
