Here is a custom template I've designed for my LaunchBox. But guess what? I'm so generous, I'll let you have it, too!
If you're proficient in using Adobe After Effects or Premiere, or whatever video editing software you use, you can decorate this frontend with all the images and videos of all your favorite titles for the platform, as long as they're in your collection. The music included in this frontend is "Game Cube (Rap Beat) - G.B Kiaku Army", which has also been edited to include a familiar whisper you've heard in commercials for the platform in the early 2000's(if you're American or Canadian that is!).
Have fun and enjoy!
