D1X-Rebirth is an interpreter for “Descent 1”. It needs “descent.hog” and “descent.pig” from original 1.4a version of the game. The sound effects work correctly and for the music you need to extract timidity folder on SD root (but if the music is on, it causes problems and hangs at the first level).
