Koala Painter - C64

[Darendor]

Anyone here ever use Koala Painter for the C64?

I need the documentation for it.

I found a reader program that uses DATA statements to input the ML portion (the code that displays a Koala Painter image).

Anyone know where the code can be modified to only output a portion of an image instead of the whole thing?

Although it is for the Atari version, maybe this will help you:

There are plenty of modern programs which handles the Koala Painter format like a dream. Pixcen seems like the obvious choice (https://csdb.dk/release/?id=174343 or https://censordesign.com/pixcen/versions/?C=M;O=D).

Why are you trying you output a part of the picture? Are you trying to make 76 x 86 pixels Bard's Tale format pictures? If that is the case, you should be looking for a pixel-editor supporting the Apple II interlace format.
