Issues fixed

Technical Issues

This game must be run under DOSBox. Being a demanding 3D game in software mode only, even modern computers have trouble running the game at acceptable frame rates. DOSBox Staging offers significantly better performace.
Mouse movement may stop working on occasion. Save and restart the game to fix.

Bad Performance

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 crashes if DOSBox is set to Dynamic CPU mode. This patch fixes that issue, allowing the game to run with smoother frame rates, even at higher resolutions.

Music does not loop (DOSBox)

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.
