The Cave Mouth
This is the standard JSW48 altered when I was writing the DefRoom editor. These files include a menu front-end that allows you to turn various extra features on and off.

It has the following patches:
  • The Attic, Interface 1 Pause and Block Graphics bugs are fixed.
  • Extended to have seven-bit room numbers, so increasing the number of rooms to 72.
  • You can return to BASIC without clearing memory by pressing SS-Space from the introductory screen.
  • If ROOM+&ED has bit 7 set, it specifies a sprite page to use for the player sprite [Geoff, Broad, Elliot].
  • The Nightmare Room has ROOM+&ED set to &B6 to specify the flying pig sprite for game engines that implement room-specific player sprites.

    The extra rooms have allowed me to fill in some of the the gaps in the game map:
  • between the East Wall and the Bathroom and Chapel,
  • between the Wine Cellar and the Security Guard,
  • under the kitchens and hall.

    Most of these are empty, but three are filled:
  • Room 47 - April Showers - Your Spectrum, April 1985
  • Room 62 - Cave Mouth - Greg Heslington
  • Room 63 - The Cave - Greg Heslington

    You could gain access to the extra rooms by extending the ledge in Halfway up the East Wall [32] to become an exit leftwards to Room 94, and allow the ladder from Ballroom East [20] to go up to Room 95. There is also space for an extra room between The Attic [41] and Dr Jones will never believe this [40].
