A Modchip, a portmanteau of "Modifying Microchip" is a device used to circumvent the digital rights management of many popular game consoles, including those made by Microsoft (Xbox series), Sony (Playstation series), and Nintendo (Gamecube, Wii) for the purposes of playing back-up, imported, pirated, or homebrew games and/or applications. They are used mostly on systems that are CD/DVD-based due to it's ease and the availability and low cost of blank media.
