Every gadget gets hacked sooner or later, it’s just the way things go. Some people get bored and can’t help themselves not hacking something to make them different, unique. In this case, you’ll be learning how to install a Wii modchip.
The WiiKey modchip doesn’t actually go on the Wii’s motherboard, but the DVD drive’s motherboard, effectively sitting between the DVD subsystem and the Wii’s DVD interface, and it tells the Wii that any disc inserted into the drive is an authentic disc of that Wii’s region. The Wii never suspects that the DVD drive is lying, and that’s why the modchip allows you to play backup up games, homebrew, and so forth.
