For SOD I would recommend that you try the new patch by New Rising Sun:
QFG4 CD.
Fixes:
- Antwerp maze is no longer linked to the "Speed" slider setting
- "Error 47" at slime slope
- Ad Avis respawning after being killed
- Stamina use while crossing chasm hand-to-hand
- "Error 52" in swamp with "Chernovy"
- Wraith draining health
- Combat timing
- Missing mouse pointer when exporting character (endgame)
- Death screen animation
- Freezing in rm250 (Monastery with Igor) when using the Windows version
- Wisp animation
Make sure that you have completed the full install. Then unzip the patch into the QFG4 folder and your game should run fine.
