Template:Infobox homebrewapp Gecko OS (formerly Gecko Region Free) by Nuke lets you load Wii games from other regions.
Load boot.elf from Chain Loader. Insert any Wii Game and press reset. Enjoy your region free gaming. As of beta 5, Gecko OS works correctly with the Homebrew Channel.
GeckoOS includes the latest version of the Region Free app, which works with the Homebrew Channel. The latest version has increased compatibility with more games supported and issues running US games on PAL consoles fixed.
Note that while GeckoOS will enable the US Rock Band to load on a non-US console the guitars and drum set will not work (no controller ID lights lit). To load Rock Band try Menu Loader instead.
Cool Additional Bonus (optional)
If you own a USB Gecko it will install a remote debugger and screenshot engine into memory and will hook. This means you can load Gecko Tool version included and grab screen shots and use the remote debugger in any Wii game. This is all done on the fly and silently. Users without a USB Gecko, the remote debugger and screenshot engine is just ignored and has no effect on your game play!.
Gecko OS/Gecko Region Free was created with the homebrew libogc library. No certs, TMD, Tik, keys or other Nintendo copyright material were used or attached in the file, making it a pure homebrew release. No Datel code was used either, so please don't call this a clone etc as this and Freeloader work in completely different ways.
The decryption is done by the hardware, not in software and the correct IOS version of the game booting is selected and used. This is done by reading the information off the DVD using the low level read commands and then passed back to the starlet.
My own apploader was written, and will completely ignore the update partition, no patching is done except a region flag which is required.
This of course only works with Wii games.
Ocarina is a cheat homebrew, now integrated in Gecko OS.
Ocarina checks the GAME ID like RZDP01 for Zelda Twilight Princess (PAL). Then it checks the inserted SD card whether it can find a cheat code file for that game: in this case it would have to be named [sd]:\codes\rzdp01.gct.
To create GCT files, a PC application (Code Manager) was bundled in the package and now is available from the Gecko OS forum : http://wiird.l0nk.org/forum/index.php?topic=597.0
This application is coming with 2 sample files : rsbe.txt and rsbp.txt (Smash Brothers NTSC-U and PAL respectively). Using the File menu you can open them and select the cheats you want.
Note that unlike an Action Replay, you can modify codes with XXXXXXXX inside them. It will always ask you to store modifications to its application memory.
Once you're done selecting codes: click on "Export to GCT" and the rest should be pretty straight forward! Codes can be found here : http://www.usbgecko.com/codes/
- Moved rebooter to a menu item
- Fixed a bug that prevented the codes and patch folder from being found if in data/gecko
- Fixed a bug that caused a core dump if background.png is in the root directory of the SD card
- Language and video mode settings from WiiRD are now used if a game is started from WiiRD
- Fixed a rebooter bug that caused the currently inserted game disc not to show up in the disc channel
- Added channel loading with hooks, channel menu supports same database.txt format as AnyTitle *Deleter MOD to replace the channel IDs with channel names (put database.txt at the root of the SD card)
- Ocarina works on channels
- ELF/DOL loading from geckoload now works
- Optionally the directory data/gecko can contain the codes folder, patch folder, gameconfig.txt, config.dat, and background.png instead of the root of the SD card
- GC memory cards are no longer detected as a USB Gecko
- Changed how exit works; if a loader other than the homebrew channel was used (or an old version of the HBC) it will return to the system menu
- Fixed a text overlapping bug that would happen if a disc error occurs and Ocarina is on
- GC memory card crash fixed thanks to Nuke
- A core dump that occurs on some Wiis when launching certain games should no longer occur
- Fixed code list start for gameconfig.txt
- A minor Ocarina fix to ensure ASM insert codes will work properly
- Exit no longer causes a core dump if Gecko was launched by a loader that lacks return to loader functionality (such as preloader); instead exit returns to the Homebrew Channel, or resets the Wii if the Homebrew Channel is not installed
brkirch has released Gecko 1.8 the successor to the Gecko OS. This unofficial build has been approved by the people responsible for the USB Gecko Nintendo Wii hacking/cheat code device. It has a lot of new features and a new GUI.
The Gecko homebrew application can be used without the USB Gecko hardware, but you're limited to only using it's various non-integrated features. However, the features available are worth using including cheat code support, region free gaming and much more!
- Multidol games work through Gecko's game loader, rebooter is no longer required for them
- To ensure games are fully functional the game loader now uses the IOS requested by the game (as a result there is no 002 error, that error is due to game loaders booting a game with the wrong IOS)
- If a game requests an IOS that you don't have, the game's update partition will be searched for the IOS and the option to install the IOS will be given if it is found (if you have a modchip, turn off update blocking!)
- It is now possible to select not to load the debugger, which increases the number of code lines allowed by Ocarina
- New hooks have been added so that most (if not all) Wii games can be hooked
- Rebooter will use the hook selected on the config menu to hook games
- Rebooter is now compatible with preloader
- The menu interface has been improved, and you can load a custom background by creating a 640x480 PNG-24 file, naming it background.png, and putting it at the root of your SD card
- The menu configuration can be saved, and the saved configuration will be loaded automatically when Gecko starts
- A configuration file can be created for game specific settings like hook type
- New code types are supported by the code handler
- GPF (gecko patch file) support
1. No copy flag bit in saves now removed when copying no copy flag save games.
In previous version you could copy no copy saves but it left the no copy flag bit in the save so unless you used a Hex editor you couldn't copy the save game back to your Wii. Now this bit is removed when you copy the save over. Thanks Kenobi for this patch.
You need the rebooter to copy no copy saves to SD card, but of course you can copy them back without rebooter loaded just like any other standard save.

Please note I take 'no' responsibility for the use of this software, If a game doesn't work you can report this in the USB Gecko forums, and I will try to fix it for the next release. It has worked on all games I've tried however I can not afford to buy all games so will need beta testers :) This will NOT work with backups without a modchip.
Xt5, Shagkur, Y.S, Bushing, Costis, Dhewg, Pinchy, Segher, TMBinc, brakken and tehskeen.com and all Gecko beta testers!
