Gecko OS (formerly Gecko Region Free) by Nuke lets you load Wii games from other regions.

Instructions

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 has 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!.

Technical Jargon

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

Ocarina is a very simple Wii application for your homebrew channel. (Now in GeckoOS) What it does? Start a game.. but there's a twist of course.

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 name [sd]:\codes\rzdp01.gct .

To create GCT files.. a PC application is bundled in the package. This application is coming with 2 example 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 I added this question so that people do not cry if a code is messed up - the actual cheat code file will not be modified until you save it in the app.

Once you're done selecting codes: click on "Export to GCT"... and the rest should be pretty straight forward! Insert your SD card.

Changelog

GeckoOS 1.07b

---

Whats new:

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.

Disclaimer

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.
