ColecoVision and TMS9918 Multicolor Thursday, 3rd April 2008

One notable gap in my TMS9918 (video) emulation was its "Multicolor" mode. This mode broke the screen down into 4×4 pixel squares, resulting in a 64×48 grid. Each cell could be assigned a unique colour, giving you a crude bitmapped video mode. No Master System or SG-1000 software used this mode to my knowledge, which reduced the likelihood of it being supported at all (if I could't test it, how could I emulate it?) I was tipped off that some ColecoVision software made use of it, so set about emulating the ColecoVision.
