Unfortunately your SoundBlaster compatibility isn't since the SBMIDI.EXE driver/player isn't compatible with the SoundBlaster 1.0, 1.5, or 2.0 (it only works with SoundBlaster Pro and later). You may either want to find/make a SBMIDI.EXE that works with the original SoundBlaster 1.x/2.0, or change your stated sysreqs.
