Another open source modchip for PIC 12F629, 12F675, 12F683, 16F628, and 16F628A chips. It is written in JalV2 and the source code is always released with the binary. It has all the functions of a regular commercial modchips but it's free. To update WiiFree the chip needs to be reprogramed with a Pic Programmer. Development of WiiFree has been discontinued. The developers recommend using YAOSM for a comparable solution.

Availability: Available (but development discontinued)

A PIC-based kit made for easy install into any project requireing a PIC 12F629. The kit includes a PIC 12F629 chip mounted on circuit board, an external header that gets wired in, and a JDM programer. Programming software is available on the site and works with any JDM programer that supports the 12F629.

The Wiikey, released February 2007, was one of the first DVD-upgradeable modchips to be released for the Wii. It is a first generation chip, and can only be installed on systems with chipset revisions of D2B and older (including systems with “cut” IC legs). The Wiikey has six points to solder on to the DVD drive. This can be done either via wires or through the "quicksolder" method.

The Wiikey’s firmware works by a process of funneling through the debug serial port. This effectively tricks the DVD drive into believing that the backup is in fact legit, much like current Xbox 360 chips do. Periodic firmware updates are released from the Wiikey development team, as well as configuration discs used to change the Wiikey settings. Both can be found on the Wiikey website.

In addition to complete original Wii functionality, including system updates and online game play, the Wiikey packs an impressive list of features. As of the 1.9s update the Wiikey supports:

    * Direct Boot of Wii Backups
    * Direct Boot of GameCube Backups
    * Direct Boot of Homebrew in GameCube Mode
    * Direct Boot of Different NTSC Region Wii Games/Backups on US and JAP Consoles
    * Partial Support for NTSC Region Wii Games/Backups on PAL Consoles
    * Boots Different Region GameCube Games/Backups (Partially Without Swapping)
    * Supports Multi-disc Games for Both Wii and Gamecube
    * Supports DVD-R / True DVD+R and +RW Support (No Bitsetting Required!)
    * Supports Full-size 4GB Discs for GameCube homebrew
    * Stealth Mode
    * Recovery Mode - Can Recover from a Bad Flash
    * Super Mario Galaxy Protection Workaround
    * Dual Layer Backup Support for Super Smash Bros. Brawl

As of March 26, 2008, there is support for original versions of Dual Layer DVDs, (including Super Smash Bros. Brawl). The update labelled '1.9s' is available on the Wiikey website.

The first announced modchip for the Wii. Supports playback of backup discs but only in the format of its own region. The Wiinja Deluxe, released on February 26, 2007, can upgrade and play imports. The original Wiinja, however, lacks this function and cannot bypass the newer Super Mario Galaxy copy protection.

In June 2007, Team Xecuter announced the "Wiip2" modchip to remedy several hardware related shortcomings of the original "Wiip" project. Their web site featured a thorough description, discussions and prototype pictures, however, by now all Wiip2-related material and forum threads as well as the pre-order possibility have been removed from their web site.

Another drive chip for the Wii. The installation of this chip is moderately different as the chip is grounded on two points, and requires a separate wire to be soldered for the update function. Also, it requires ANOTHER wire to be installed if the user desires to play multi-disc games. This is the first modchip to have a quick solder option, but require wires to be installed for multi-disc functionality. The installation is difficult, and the functions are less than par.

A free PIC-based modchip written in GCBasic. It started as a rewrite of the popular WiiFree and it is the first modchip to use automatic region configuration, as well as the first open source modchip to let users set the DVD Drive's speed via Setup Disc. It's always released with source code and precompiled hex files for a wide range of suitable PIC chips (12F629, 12F635, 12F675, 12F683, 16F627, 16F627A, 16F628, 16F628A, 16F630, 16F636, 16F639, 16F648A, 16F676, 16F684, 16F87 and 16F88.) From v2.0 and on, it also supports audiofix for GameCube games, as well as Super Mario Galaxy backup (from v1.9) and DVD-9.

Availability: Available (Released in April, 2007)

A modchip for the Wii that can be reprogrammed with any precompiled hex file that supports the PIC 12F683. Since it isn't limited to a particular modchip hex, the feature list will be based on the hex the user decides to program it with. It does however come pre-programmed with Yaosm hex. Because the Yowii chip uses the larger PIC 12F683, the full version of Yaosm fits on the chip without the need to remove features. It also supports the Super Mario Galaxy fix (SMG fix). It offers quick solder install or 5-wire install. The 5 wires are attached to a plug which then plugs into a connector on the chip. The same connector is also used for programming the chip and the wire is long enough to attach the chip externally.

D2CKey has been designed with user simplicity in mind. After installation, it just works. There is no need to set up, reflash, upgrade, or fiddle around. D2Ckey automatically detects what kind of disc is inserted, and configures the drive accordingly. Original and backup original Wii and Gamecube games from different regions with the same video system boots directly, and even a lot of games from regions with different video system can be booted directly. Gamecube audiostreaming fix is built-in from the start.

Compatible with most DVD+/-R and RW media (no bitsetting required) and multigame discs.

DVD-R, DVD+R, DVD-RW, Dual Layer DVD, bitsetting... finding the right recordable media and the right burner isnt always that easy. Some kinds and brands of media and recorders might work better with the Wii drive than others. D2Ckey offers support for most of them from the start, making it simpler for you. While a certain media, burner, or combination might not work properly with a certain drive, it will be easier to find a working combination knowing that d2ckey supports most of the common recordable media types.
