Covers

Pico Launcher supports showing covers for any kind of file by placing .bmp files in the right folders.

Where to place covers

Covers are placed in subfolders of the /_pico/covers folder.

• The /_pico/covers/nds and /_pico/covers/gba folders contain DS and GBA covers, respectively, by game code. For example ABCD.bmp.
• The /_pico/covers/user folder contains covers for specific file names. For example myGame.nds.bmp will be used for any file named myGame.nds. This takes precedence over a game code based cover. Since most consoles other than DS and GBA don't have game codes, this folder is suited to provide covers for games of other systems, for example NES or GB(C).

Cover format

The covers should be 8 bpp (256 colors) .bmp files of 128x96 pixels. Only the top-left 106x96 pixels are used. The remaining part on the right is padding and is ignored.

Example

Note how the black part on the right is not used.
