Sound

Perentie is designed for the limits of MS-DOS audio hardware: music using an OPL2/OPL3 chip, and sound effects via the PC speaker.

OPL2/OPL3 Music

Perentie supports playing music using a Yamaha FM chip; namely the YM3812 OPL2 (AdLib, early SoundBlaster) and the YMF262 OPL3 (SoundBlaster 16).

Under DOS this is done by accessing the hardware through the standard port (388h), whereas modern builds use a bundled copy of the DOSBox project's WoodyOPL OPL3 emulator.

As of now, the only supported music playback format is Reality Adlib Tracker v2, but we hope to add support for playing standard MIDI files soon.
