Issues fixed

Technical Issues

This game must be run in DOSBox as it is a DOS game. As it is a demanding 3D game within DOSBox, it requires modern processors to run at acceptable frame rates.
Mouse movement may stop working on occasion. Save and restart the game to fix.

Performance Fix

Performance Fix[citation needed]
  1. Patch the game to the latest version (csmtcpip.exe).
  2. Download this fixed .exe file
  3. Replace the PS10.exe in the installation folder with the fixed version

Notes

Without this fix the game would crash if DOSBox was set to 'dynamic CPU' mode, and without that mode the game would run at an unacceptable FPS regardless of how powerful the processor was. This patch fixed that, allowing the game to be run at 640x480 resolutions at smoother framerates.

Music does not loop (DOSBox)

Without this fix the music does not loop in DOSBox, playing only once.
Music Fix[2]
  1. Download CTRLOOP.exe and place it in the installation folder
  2. Configure DOSBox to run CTRLOOP.exe before launching the game.
