| Feature | Notes |
|---|---|
| MIDI music | MIDI music plays differently in Chocolate Doom. DOS Doom programmed the OPL chip on the SoundBlaster directly; Chocolate Doom uses the generic MIDI interface found on modern Operating Systems. OPL emulation needs to be added to make the experience more authentic. |
