No, an emulator is a piece of software so you can play other computer games from other consoles on another system.
There is no Wii emulator for PC. This thread is about emulators for Wii, like SNES, NES, Megadrive, NEO Geo, etc running the roms on your Wii.
There is a way but it is emulators for gamecube which allow you to run these on your Wii but you need a modded Wii.
