There is another way to dump entire game maps. As an example I will use Beyond the Beyond game. It stores game map at the end of RAM as a 128x128 array:

Changing it's content automatically updates game screen, so we can use the following alghorithm:
1. determine the location of viewport
2. using a simple script, blit there a chunk from the other part of the map
3. save a screenshot
4. repeat to 2, until all chunks are saved.
5. use ImageMagick to combine all screenshots into one big image.
