Resource Tools

Patches

  • No Official Patch


New Installer

Works for both 3.5" and 5.25" versions. If you do not have DOSBox installed, you must be online to when you install the game to allow the installer to download and install DOSBox for you or the audio file will not be decompressed. To accommodate PCs without a floppy drive, for the floppy version this installer is designed to work by using the files from the original media copied to the harddrive. Because some files are named the same, the files from multiple disks often need to be kept separate to avoid overwriting each other. To install these games:
  • Create a temporary folder on the hard drive.
  • Inside this folder, create a numbered folder for each disk, i.e. "1" for disk 1, "2" for disk 2, etc. one for each disk.
  • Copy the contents (files and folders) of each disk into its appropriately numbered folder,
  • Copy DOSBox installer for the game into the same temporary folder.
  • Run the installer from this same folder.


Debug Modes

The "magic" script is 98, which has been disabled in the game, along with removal of the debug build of the interpreter. The attached contains the debug handler script and other debug files, a debug build of the interpreter with debug help files. Just extract and drop into the base directory of the game and start the game in DOSBox for full debug options.

Credit for fixing the debug handler script goes to doomlazer[4] of the SCIprogramming community. Credit for the debug build of the SCI1.1 interpreter goes to "Kawa" of the SCIprogramming community.

Upon launch with these files in the game's base directory you should see a "Where to, Mac?" prompt immediately.

Besides giving you the "Where to, Mac?" dialog at the beginning, the following options are available:

'?' will list the below debug commands available with the script debugger:

Command Action Notes
[ALT + A] Show cast Information about all objects on screen
[ALT + B] Show flag value
[ALT + C] Show control screen
[ALT + E] Show ego information & free memory
[ALT + F] Show Features Displays name of current feature under cursor
[ALT + G] Set Global
[ALT + I] Get inventory item Allow selection of inventory item from list
[ALT + J] Note Logger for QA Does not work
[ALT + K] Set Flag
[ALT + L] Clear Flag
[ALT + M] Show Memory
[ALT + O] Create Obstacles Causes out of heap error
[ALT + U] Return user control Does not work
[ALT + P] Show Priority screen
[ALT + R] Show Room info
[ALT + S] Switch mouse actor ???
[ALT + T] Teleport Change room/scene/script
[ALT + U] HandsOn Return user control
[ALT + V] Show Visual screen
[ALT + W] Write Features
[ALT + X] Exit the game
[ALT + Y] Show pallet
[ALT + Left Mouse Button] Instant movement/placement If walking
[CTRL + ALT + Left Mouse Button] Print mouse X/Y
? Help List debug commands

To invoke the interpreter debugger press the grave accent (`) or [Shift + Shift + Number pad '-']. Note, if you have not started the game with the included debug build of the interpreter (SCI.EXE) the game will crash. Pressing "?" while debug is active will display interpreter debug commends.
