Most Win98 games run on XP thanks to built-in compatibility shims, but exceptions exist.
| Problem | Cause | Fix |
|---|---|---|
| Won’t start | 16-bit installer (Win95 era) | Copy installed folder from Win98 VM; or use DOSBox |
| Crashes / graphics glitches | DirectX version mismatch | Install DX9.0c (June 2010 redist); try dgVoodoo2 |
| Speed issues | CPU timing loops | Compatibility mode → “Run in 640×480” / “Disable visual themes” |
| Copy protection fails | SafeDisc/SecuROM kernel drivers blocked in XP SP2+ | No-CD patch (legal gray); or GOG version |
| Audio missing | DirectSound3D/A3D dropped in Vista+ | Creative ALchemy (if Creative card); or IndirectSound wrapper |
GOG.com versions come pre-fixed – best $5–10 spent.
