Console hackers have released a modchip for the Nintendo Wii console. The Wiinja modchip is a coded IC that is able to bypass the copy-protection on the Wii, enabling you to make backups of your games or run pirated games:
The modchip is reminiscent of hardware mods from the days of the original PlayStation, requiring five wires to be soldered directly onto the Wii’s motherboard. It should go without saying that the console must first be dismantled and that the entire process would completely and utterly void the warranty.
As proof of the modchip’s operation, the developers have posted a couple videos on YouTube, demonstrating a Wii loading games burned onto recordable DVD media. A method to backup Wii games was revealed earlier this month, though the process of creating a disc image could take in the neighborhood of about fifty hours.
Currently there's still a restriction that you'll only be able to boot games with the same region code as your console.
