Description

Currently program detects the most used of 16 colors and use it as a background color when saving to c64 (koala) format which is often useless. It would be great if on the save form user could select the background color manually (0-15). It could be by default be set to determined most used color for the first save or the previously selected color for the subsequent saves.

Out of curiosity, what is the consequence when the "wrong" color is chosen ? I mean, is it only that the file is inefficiently compressed, or does it have another effect on the C64 ?

Is it useful for someone who opens a Koala file to know which bg color it is currently using ? And to change this color later (For example if picture changes a lot, the "best" BG color may need change) ?

I have studied the Save_C64_multi() code and things are a bit more complex.
The background color is common to all 4x8 tiles that have 4 colors.
So this is not the "most used of 16 colors" which is chosen.

If there are 2 or more colors common to all tiles which have 4 colors, the lower order one is chosen.
In that case, that could be relevant to ask the user.

In the process I have noticed a few bugs, I'm fixing them.
