It's unclear why this apps print the MCI error text corresponding to
MCIERR_UNSUPPORTED_FUNCTION.  It does not use the MCI at all!

It uses winmm:midiStreamOut() to play the music instead.  A hint to the
possible fault appears only when waiting for music to start in demo
mode, instead of going to the high scores:
fixme:winmm:MMSYSTEM_MidiStream_MessageHandler Dropping bad stream lpMidiHdr
(streamID=30315f79) [that's "01_y"]

There may also be some buffer overflow involved. A log with warn+heap gave:
warn:heap:HEAP_ValidateInUseArena Heap 0x110000: invalid in-use arena magic
00555555 for 0x135f700
This address is near one used for MIDI:
trace:winmm:midiOutPrepareHeader (0x8000, 0x135f708, 64)
fixme:winmm:MMSYSTEM_MidiStream_MessageHandler Dropping bad stream lpMidiHdr
(streamID=55555555)
55555555 looks like the bad "arena magic" above.
