Game Name?
Gecko 1931 (Included in Project M)

Game ID?
...There isn't one?

What's the problem? Describe what went wrong in few words.
Upon loading Gecko OS, the screen will stay dark green and it will freeze.
Loading System Menu 481E after, you will be presented with "The system files are corrupted."

What did you expect to happen instead?
Well, I expected it to work and show Project M's custom gecko os background. And the wii system menu to actually work.

What steps will reproduce the problem?
[Don't assume we have ever played the game and know any level names. Be as
specific as possible.]

1. Use NAND extracted from wii
2. Load gecko
3. Quit and load wii system menu
