Add 16 Color support #13

Closed wrightsl closed 5 years ago

wrightsl commented 5 years ago

Based on the version from http://saanlima.com/forum/viewtopic.php?p=1793#p1793 which uses a 16 color palette at address -128.

To use, you will have to compile Display.Color.Mod, and then restart the emulator with the --color switch. If the switch is not set, the emulator behaves as before (except it will use a larger display memory).

Display.Color.Mod contains a hack so that if white=1, white gets copied from color 15 to 1, and black from 0 to 14. That way, you can avoid recompiling the whole system. If you recompile the whole system with white=15, the hack disables itself automatically and all 16 colors can be used.

For the record, I discussed that change with @pdewacht on IRC, and he said he would not want to merge any color support as long as color support was not added to the original sources on Prof. Wirth's website.
