X-Delusion posted this rather exciting news over at http://homebrew.dcemulation.org :

As if Bero’s new ports were not enough, I dicovered a Deh file for the commercial TC that never was: HacX, so now it can run on the Dreamcast, and seemingly with no problems! All items are breakable, from chairs to glass windows, new enemies, new weapons, ect! It is like Duke Nuke’m on the DOOM engine, I swear!
And if that was not enough, I have also been working on porting the DOOM 64 graphics over to the DC, by barrowing sprites and sounds from some other DOOMer’s projects, so far everything seems to be running flawless once again, and the kool thing about it, is it REALLY brings those old Megawads back to life such as Requiem, and Memento Mori 1 and 2!
Head over to the DOOM page and check it all out!!
