‘A Wii modchip without the bullshit.’

A first in the modding scene – TCNiSO Corporation has developed an open source modchip for the Nintendo Wii. With a slogan of “A Wii modchip without the bullshit” the are making it possible for DIY’rs to fabricate this chip by their own means. They estimate it will cost a mere $10 to build this chip from common place electrical hardware. For those not so ‘Hands On’, they are making it available for purchase for only $20 (includes shipping). They are taking mod chip development to a new lever by keeping the price incredibly low as well as releasing the source code, schmatics, and tutorials to build this from scratch.

The current features of Wiip are:

  • Actually upgradeable! Device is bundled with an easy to use programming cable
  • 20 MHz AVR microcontroller with 2KB of EEPROM (SMD type)
  • Customizable (via open source code)
  • Boots Wii games (DVD+R / DVD-R media)
  • Boots GC games and homebrew
  • AudioFix (naturally)
  • On board DIP switch (enable/disable mod, enable/disable stealth)
  • Works on DMS / D2A chipsets (sorry, we haven’t worked on D2B yet)


Wiip is a hardware mod for the Wii system that allows you to boot backup discs. This mod works by utilizing a cheap and simple microcontroller that communicates with the serial port of the Wii’s hybrid DVD drive and overrides certain parts of the media’s data stream. Allowing you to do all sorts of wonderful things (like boot backup discs).

The most important part of this project, is that it is open source! In addition to releasing the Wiip chip, on this page you will soon be able to download the PCB schematics, Wiip firmware and documentation! We hope by creating this project, other users will make modifications to our code for newer updates in the future (if needed).
