And right now it's easier to install it than ever. No need for stupid zelda game and what not.
Want to be able to watch DVD's on your Wii? Or any movie/audio file? Stream music/audio from the internet?
Want to play 10's of thousands of games for just about any game console that came out in the past 20+ years?
As we speak, I'm uploading 7000 games for Atari 2600, 7800 and SNES. (thank you Demonoid).
For those interested, here is the almost idiot proof way to get homebrew channel on your Wii:
Download, extract and copy the homebrew browser to your apps folder on your SD card:
in the latter you can browse thru some homebrew games, utilities and media programs, than download and install them straight from the wii if you like. Those include most emulators for other consoles, simple FTP server (so you can move files between the Wii's SD card and your computer) and bunch of other goodies.
This really made the Wii 100x better.
I'm fixing to deploy with bunch of guys again, and I'm making sure we got entertainment for months
