As of MelonLoader 5.3, you can now customize the startup screen! Place the "MelonStartScreen" folder for the startup you want in UserData to apply the theme. Updated to include a Saberlake Version as well as an improved gammon one.

Make sure you delete all files from the "MelonStartScreen" folder in UserData before applying a new theme, otherwise parts of the previous theme might appear in the new one.
