Well, then it would be the 40-column mode, one color for the text (screen and text identical to "Chateau Du Dragon").

But the title screen would be a problem. For the Commodore-64, it would be 200X320. On a ColecoVision, it would be 192X256. While the difference in vertical resolution isn't much to worry about, that 25% difference in horizontal resolution makes a straightforward translation out of the question.
