This page started out of a desire to revisit the text adventures of the 1980s that I enjoyed so much as a child/teenager and study how they were written (as well as finding the hidden easter-eggs that I may have missed in my original playthroughs). I came across a tool called UnQuill and, using this to work out the Quill data format, wrote my own tool for reverse engineering Quill games into HTML pages. The guides below were based on the output generated by this tool with maps and walkthroughs added.
These guides include a breakdown of the full Quill source code, reverse engineered from the original ZX Spectrum and Atari game snapshots.
