WiiLauncher is a simple alternative to Gecko OS application. It has most of the Gecko OS features and has additional features for downloading and editing cheat codes.

WiiLauncher automatically reloads and patches IOS 36 so there is no need to install unofficial (patched) or even custom IOS to run the channels (with the debugger or cheat codes) or the rebooter features. Full hardware access (AHBPROT) is used when applying such run-time patches. This access could be obtained by running WiiLauncher application from Homebrew Channel (version 1.0.7 or higher).

Important notes

This wiibrew application has not been tested extensively, use cautiously. Since it writes to SD card (for saving the configuration and downloading cheat codes features), make sure you have a back-up of your important SD card content.


  1. WiiLauncher starts at the main menu
  2. On the top section, it shows whether USB Gecko is available and whether WiFi-Debugger feature could be used (to record the debugging messages when running this application requires having WiFi access and running WifiGeckoReader PC application)

What is the meaning of [?] symbol in front of the name of the cheat codes?

The symbol indicates that the cheat codes cannot be used without editing it. One or more cheat codes rows contain non hexadecimal characters

I cannot toggle that [?] symbol to be either On, [+], or Off, [-]

You need to edit the cheat codes first and once it is done, the application automatically changes the flag or symbol to be Off, [-]

Can I use this with Wii-U for WiiMode?

Yes, you could
