These files store graphic data created by Koa Painter on Commodore Amiga systems. They also appear as Commodore 64 graphics files from KoaStudio work environments.

  • Opening these files usually requires software tailored to Commodore graphics.
  • Conversion or emulation tools may be needed to view them on modern PCs.
