In general Gamepacks can be configured using the controller. However, the Gamepack "menu system" does not shows on the TV screen. It just flashes the LED on the controller. Counting the amount of flashes you can navigate between the MODs Classes and MODs settings. This process is not intuitive and, for Gamepack configuration, I strongly suggest to use the Gtuner's Gamepack configuration interface. On Gtuner, after you drag-and-drop the Gamepack into a memory slot:
1) click on the memory slot number.
2) A window with the gamepack configuration will open.
3) Enable the MODs you want.
4) Yet on this window, select the option: "Include configuration on programming device", as illustrated here:

6) IMPORTANT: Commit the changes on the device by clicking on the button "Program Device".
7) Plug the device on the console.
8) Press the device button until the display shows the same memory slot number you programmed the Gamepack.
9) You should be ready to go!
