Description
A Commodore 64 picture in the BML variant of the FLI Graph / FLI Designer format, a 320x200 image with 16 colours. It starts with the two bytes 00 3B, where the sibling FLI format (the fli type) starts 00 3C. The extension is the only reliable signal, so BML files are recognised by their name.
