A few weeks ago, an announcement was made the “Homebrew Channel” had been released for the Wii. What that is, is a channel for your Wii that allows you to boot homemade games, emulators, applications and demos on your Nintendo Wii. The channel is very well put together and looks very professional once it is installed.
It should be noted that this channel is not an official Nintendo release. This channel was developed by independent programmers, as is all of the software that can be run through the channel.
There is already quite a long list of programs that you can download and run through the Homebrew Channel. I have installed it on my Wii and am extremely impressed.
You can find all the pertinent information at WiiBrew.org.
