A small tool that crops a given Koala image to a smaller image cut out by a given window.
The result is a much smaller file, that contains only the graphic blocks selected. Note that this needs a different display routine, an example for such a routine is included as ca65 assembler code.

Usage: cropkoala.exe [-i <infilename>] [-o <outfilename>][-x X][-y Y][-w width][-h height]
-i file in Koala format to be read
-o File to be written
-x starting X coordinate from 0..319
-y starting Y coordinate from 0..199
-w width in pixels
-h heigh in pixels

x coordinates go from 0 to 319, but they should be always a multiple of 2, since a Koala images are always in multicolor format.

Btw, if you want to cut out an area while keeping the overall image in the Koala format, have a look at this tool Koala Tool
