Is there a way?

Can you download a nes game on your pc and then transfer it to you wii? It seems that their is a way but I havent figured it out yet.

have you tried looking for the emulator packs on a site like isohunt.
I found lots of games and emulators. Im not sure what mod chips they work with, but its worth a try.
So get a torrent d/l utility, and go to isohunt, search for Wii emulator and see what comes up.

I dont have a modded wii. Just hoping for a way to tranfer nes games from pc to wii, maybe using the sd card.

erm no, you can't do that man. VC games are not just rom dumps

look into an SD Launcher or Datel Homebrew if you dont have a mod chip
