December 2023 - Apple II version by Antoine Vignau & Olivier Zardini.

Cauchemar House
(c) 198? by an unknown author

What is Cauchemar House?

The original author name is unknown. Cauchemar House was found on a hoebrew cassette by XavSnap. The engine uses the adventure engine published in The ZX-81 pocket book book published in 1981. It was one of the earliest, if not the first, title of that sort in French for that machine.

We wanted to port it to the Apple II as the platform lacks so many interesting French games of that era. We even made an English port. We also thank XavSnap who helped us in using the right and reliable data. We made it in assembly, as usual :-)

How to play?

Enter one or two word commands (eg. OPEN CLOSET, NORTH) and press return. If the command is recognized, the game engine will act accordingly. If you are stuck, please refer to the manual which contains the solution.

Some commands were added to the Apple II version:

  • CASSE (EN: CASE) to switch between lower- and -upper case chars display,
  • QUITTER (EN: QUIT) to return to your preferred launcher,
  • TEMPO (EN: TEMPO) to enable/disable game tempo routines.
