Resource Tools

Patches

For floppy Version only. On a few slower computer systems, it is extremely difficult or impossible to arrest Walker in City Hall. This patch will give you more time to put the handcuffs on the suspect.

For floppy Version. Updates your copy of Police Quest to version 1.0c from versions 1.0, 1.0a or 1.0b. Fixes:
  • Lockups in the shoot-out scene.
  • Problems with Emo if the game was saved at a certain point in the shoot-out scene.
  • Not being able to scroll through cursor icons at one point.
  • All cursors acting like the talk cursor at one point.
  • Not getting the full amount of points when using the 90 degree mirror.
  • Lockups after certain DAC sounds played.
These Gravis Ultrasound Drivers will work with some Sierra 32 bit games. These drivers will not work on earlier Sierra games.


New Installer

Now works with both CD and floppy versions. If installing the CD version, it will install the entire game to the hard drive for CD-less play. If installing the floppy version, be sure you have DOSBox installed in Program Files\DOSBox before running installer. If you do not, 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

Debugging requires extracting specific scripts from the RESOURCE.00* file. Again, the Sierra Resource Viewer is the tool to use.


Police Quest 4 (Disk version)

The "magic" script is 1. Extract 1.SCR/1.HEP.
