Icon Overlays

Icon overlays change the shape or frame of game artwork for each platform.

File	Purpose
mask.png	Chooses which parts of the game art are visible
overlay.png	Draws a frame or decoration over the art

You can use either file or both.

Install an Overlay Pack

Download one from Silk, then choose it under Settings → Personalization → Theme → Icon Overlays.

To add your own files, place them in a folder named after the platform ID:

Cocoon/
└── icon_overlays/
    ├── snes/
    │   ├── mask.png
    │   └── overlay.png
    └── psx/
        ├── mask.png
        └── overlay.png

Platform IDs are listed on the Compatibility page.

Make Your Own

• Use a white shape on a transparent background for the mask.
• Use a transparent image for the overlay so the game art remains visible.
• Make the mask and overlay the same dimensions.
• A square image around 512×512 or larger is a good starting point.
• PNG is recommended for transparency.

You can also build and preview a pack with the Theme Builder.
