There are so many different modchips, that I got lost with all the features. lol. Which would you probably say is most feature rich? I've looked up WiiKey, and Cyclowiz and they seem very similar. Both upgradeable, etc... but any other feature differences? What about OpenWii? Also, this statement on the features page of the wiikey website got me wondering: "Supports fullsize 4GB discs for gamecube homebrew" Gamecube backups can be on "fullsize 4GB discs" right?
