MAME allows bezels to be overlaid when displaying an emulation. Download this http://www.macmess.org/downloads/coco3.zip file and put it in the artwork directory. When you run the coco3 driver in MAME, there will be a “CM-8″ option in the “Video Options” menu.

There is also a Color Computer 1/2 bezel available. Download http://www.macmess.org/downloads/coco.zip and put it into MAME’s artwork directory. When you run a coco3 driver in mame, there will be a “Color Video Receiver” option in the “Video Options” menu for screen 0.

The layout files have been adjusted to work with MAME 0.234 and later.
