Doom for Dreamast.
Or...nxdoom for dreamcast to be exact...Get the latest version here...
It's pretty damn kick ass. The sfx are there but the midi music you have to install are a bit crappy.
Holy crap. At this rate I will be playing more homebrew games than regular dreamcast games!!!!!!!
If you have the collectors edition of doom like I do you can use Bootdreams to burn a self boot copy of all the versions of this awesome game. Just jam those .wad files into a folder along with the midi files and burn.
The Dreamcast has not seen so much digital blood! (except when I played HotD2, RE, Illbleed, The Ring, Blue Stinger, Quake, Quake 3, Unreal T, Legend of Kain Soul Reaver, Shadow man, D2...HOLY CRAP! WHo says Dreamcast was a pussy system!?!?!?! Look at all these violent games!!!!
