Hopefully it will clear up any confusion. In the past, we shipped game-specific displays that were locked to that game. Based on customer feedback, and to simplify stocking and ordering, going forward there will be one model shipped with SIGMA firmware. Our site provides a product listing for each game but all displays ship in the same configuration.
SIGMA supports customer selection of 49 colors and three different display modes (classic dots, high-def upscaling, and scan lines). All the latest firmware for both SIGMA and the multicolor ROMs are now unlocked so that you can switch firmware using a USB flash drive.
The ColorDMD will support most WPC/WPC95 games but there are a few where mounting may not be possible... CV, BR, Party Zone and others like BSD where removal of lamps or other hardware from the speaker panel might be necessary in order to mount the LCD.
