nxDoom is a source port of Doom for the Sega Dreamcast, written by BlackAura. NxDoom supports the registered and shareware versions of Doom, The Ultimate Doom, Doom II, and Final Doom. It supports PWADs and DeHackEd patches, but only emulates vanilla Doom's features. It has VMU saving, and has sound and music when downloadable music WAD files are used.
nxDoom is based on DoomDC by crt0 and DCGrendel.
