This tool was quickly hacked together by Leseratte. It wasn't really planned to opensource this tool so the source code is kinda crappy.
For more information see this forum thread.
Just run the program with the path to a Wii game DOL file as parameter, and the tool will print a Gecko cheatcode that should fix error 60000 for your particular game.
If that cheat code doesn't work (or if the tool fails to generate a cheat code), please open an issue.
This tool is released under the AGPL version 3 license.
