+nanochess Posted September 14 Share Posted September 14 It is possible but it would require some kind of bank switching. For example, keeping a fixed area at $0000-$0fff, and switching $1000-$1fff. The Colecovision doesn't have a CHR ROM like NES, instead the video processor graphics are copied from RAM into VRAM. 1 Quote Link to comment https://forums.atariage.com/topic/372445-fpga-rombios-expanding-memory-possible/#findComment-5533270 Share on other sites More sharing options...

All of your examples only differ in colour, so the same graphic patterns can be used and a bit of code to update the colour to the one required is all you need.
