I've attached a quick .dsk file if you want to see this preview image on a real machine... or an emulator. It's your choice.
Hopefully, seeing it on a real machine will prompt a coder to take on the mission. We have a lot of GREAT coders here, it would be a shame for this project to fall by the way-side because no-one took on the task! Maybe we could have our first true CPC-Wiki community project game!
