Author: Note: In this tutorial, no commercial games were used.
And keep away from commercial ROM’s!
If you have a Wii, you can download lots of games from the Wii Shop Channel.
But Prototypes, that’s not included, and it never will.
Solution: Emulators!
What you need
Wii.
Homebrew Channel, and a way to install it (depending on your version).
An Emulator of choise.
The Prototypes (for other ones, Google is your friend).
A computer to download and place it on a:
SD Card.
After installing Homebrew Channel
Prepare your SD card.
Place all the Emulators in the /apps folder.
The ROMs depend on the Emulator (look at the README for it).
Put your SD card in your Wii and fire up your Wii.
Now, go to the Homebrew Channel.
Load an Emulator.
And load a ROM.
For SNES and MegaDrive prototypes, I’d recommend to use the Wii Classic controller, and for NES prototypes, a Wii Remote.
