Notes
- There are two versions of Zone 66 available - one that requires no memory manager (so it won't run under Windows or with DoubleSpace) and one that will work by sacrificing SoundBlaster sound effects and music (only Adlib music will work.) Both versions will work under DOSBox, but the former requires that you disable DOSBox's EMS and XMS support (but it's worth it, because the SoundBlaster track is much better than the Adlib-only one.)
- The game supports Adlib/SoundBlaster (SB) and Gravis Ultrasound (GUS) hardware, however the music tracks were composed specifically for each device, so the GUS tracks sound a little different to the SB ones. This is most noticeable during the intro sequence, when entirely different songs are played depending on whether you have a SB or a GUS. Since DOSBox supports both, you can run Zone 66 with one of the command line parameters below to hear the different songs. The shareware version doesn't include any GUS tracks by default, but there's a separate patch available which adds these tracks.
| Command | Result |
|---|---|
| zone66 /gus | Use Gravis Ultrasound music/effects |
| zone66 /sb | Use SoundBlaster music/effects |
| zone66 /adlib | Use Adlib music/effects |
- According to the Wikipedia article, Renaissance developed the CDFM tracker format capable of both digitised and FM/OPL playback in the same song. It is highly likely that this song format is what was used for Zone 66 (or possibly the .670 demoscene version which has all song/instrument information removed.)
