Ontology
Extension(s) .koa .gg
Released 1984

A popular image format on Commodore 64 computers was the one used by the C64 version of KoalaPainter, the paint program included with the KoalaPad graphics tablet.

There is an uncompressed format, and an RLE-compressed format. On platforms that use filename extensions, the compressed format may use a .gg extension.

Contents

Format

Images use the C64's standard 16-color palette. The dimensions are 160×200 pixels, though some viewers may horizontally replicate the pixels to make them 320×200.

An uncompressed KoalaPainter file is exactly 10003 bytes in size, but depending on how it was migrated from the C64 platform, it may have some unused padding bytes appended to it.

Identification

Files begin with bytes 0x00 0x60 (representing the memory address at which the bitmap would normally be loaded).
