Audio Problems

Audio problems are common in the later Sierra DOS SCI games. There's no single fix for all these games. You can try the Windows version, if running on 32-bit Windows.

Problem - Poor Quality / No Sound (Win9x and XP):
The game has no sound or the music is of poor quality.

Solution 1 (preferred):
Play the game in DOSBox. It also will work with the MT-32 sound module, if you are fortunate to have one.

Solution 2:
Use VDMSound. The game work well with VDMSound. The sound will be as good as your audio hardware, and as with DOSBox, it works with the MT-32 sound module.

Solution 3:
Play the game with FreeSCI, a third party Interpreter for Sierra's early SCI games.

Solution 4 (DOS/Win9x):
Install DOS drivers for your soundcard. Without DOS drivers installed you won't have sound in a DOS window in Windows 9x. If you can't find DOS drivers for your soundcard, there is an alpha (developmental) version of VDMS that you can try.

Game Specific Bugs

There are a couple of bugs the game has that are not speed dependent.

Problem - Can't Arrest Walker:
