There are a few different RC2014 configurations that will work in combination with the 3 game boards that I designed (video, audio, and controller).
With the RC2014 Zed Pro kit, you can load ColecoVision games from CP/M. You will probably want to add the CompactFlash module to that so you have permanent storage and you don't have to upload the games over the serial port the RC2014 every time.
A less expensive, and in my opinion, superior option is to buy the Pro backplane, 64K RAM module, and Z80 CPU module separately, then add my 3 game boards, plus my z80ctrl board. The z80ctrl replaces the ROM, clock, Compact Flash, and serial boards with an AVR microcontroller that lets you load the games directly into memory from an SD card, bypassing CP/M.
The Pageable ROM board that comes with the standard RC2014 Pro is NOT compatible, because it has a port conflict with the video card.
Of my boards, currently only the video board is available as a kit. I am working with the seller of the video card kit to offer the other 3 boards on Tindie as well (sound, controller, and z80ctrl) but I don't know when they will be available yet. Until then you would have to get the boards manufactured yourself from e.g., JLCPCB.com, and then source the components yourself from Mouser and eBay.
I have written a blog article that explains the various ways games can be loaded.
