How to Put Wii Games on USB ....and where to download games for free?

I myself haven't tried playing any wii games on a computer but you should type in "name of the game you want to download + rom" on google. You'll basically download a raw copy of the game. After you've done that, save it to your flash drive. Once you've done that, type in Nintendo Wii emulator online and just download a random on to that same flash drive. Once you unzip the file and open up the emulator, click file, open, and choose the game on the flash drive. That should work and allow you to play the game on your computer.
