I picked up a Wii earlier this year and decided to hack it to see what benefits that would provide. The results were, to be honest, quite spectacular. After spending quite some time digging through various HOWTOs scattered across the internet with often conflicting or out of date information, testing different configurations and applications, and running through quite a bit of trial-and-error, I finally have a solid and extremely functional Wii that lets me do pretty much anything I want with it. Some of the highlights include:
* Boot directly to WiiFlow (a slick homebrew launcher application), bypassing the health and safety screen and main Wii menu
* Rip any Wii or GameCube game to an attached 500 GB USB drive
* Browse, select, and launch any previously ripped Wii game from the USB drive
* Browse, select, and launch any previously ripped GameCube game from the USB drive (note: this requires a GameCube-compatible Wii)
* Play older games via emulators (though, honestly, PC emulators provide a better experience)
* Run various and miscellaneous utilities such Wii and GameCube memory card management utilities, allowing me to copy/backup saved games from the Wii or GameCube memory card to my computer
The end result is that I have every one of my 27 Wii games and and 25 GameCube games ripped and stored on the USB drive, and I can play any one of them now by simply powering on the Wii, browsing to the desired game in WiiFlow, and pressing A on the controller. No more disc swapping, and no more worrying about where to even store all of the games so they're accessible (they're now all boxed up in a closet, along with my GameCube). It's a wonderful thing. :-)
