This software runs on the ZX Spectrum Next home micro.
To run, copy the folder and contents onto your Next's SD Card, then load "Kings Ransom.TAP" from the browser. Push N for Next mode when loading. You might also want to adjust the CPU speed for more responsiveness.
King's Ransom is a conversion of a very short and simple text adventure that was given away with The Graphic Adventure Creator from Incentive Software.
This was created as part of a tutorial video on making text adventures for the Spectrum Next.
Download contains the Next game file, plus Adventuron file and the exported file ready for DAAD conversion (purely for interest to those following along with the video).
