A miniaturised ColecoVision - the console rebuilt into a smaller case.
Why it suits
- Its board is mostly empty space by modern standards, so a good deal can be removed without emulating anything. The machine that comes out the other side is still real hardware.
- Several builders have done it: doubledown's Mini CV Junior and Mini Pac-Man, Lee Krueger's Mini CV, and MyTek's CV-NUC+, which took the idea to a palm-sized production clone - all catalogued here.
What it must keep
- The controller ports and their keypads, since ColecoVision games take their options from the twelve-key pad.
- The cartridge slot, or the point is lost.
