Thanks to Zachtronics super-fan Andrew Rodland, we now have a version of 
SHENZHEN SOLITAIRE for MS-DOS that plays the SHENZHEN SOLITAIRE music as a funky 
OPL3 (i.e. SoundBlaster) track! It's absolutely amazing, to the extent that I'm 
actually a little embarrassed that we didn't find a way to make this happen in 
the original release.

Here are some technical details: 

Hardware requirements are an OPL3 or compatible sound chip. This includes the 
AdLib Gold, SoundBlaster Pro 2.0, SoundBlaster 16, SoundBlaster AWE32/64, Pro 
Audio Spectrum 16, and some Ensoniq cards. OPL2 cards (original AdLib, original 
SoundBlaster, and Pro Audio Spectrum 8) will play music but it will drop notes 
and be distorted at times  not recommended. DOSBox's OPL3 emulation is also 
fully supported. About 48kB of additional RAM is required.  Running with 
/NOMUSIC disables music playback and will skip allocating memory for music.
