LazyOne posted some more WIP news concerning his Wolf3D port to DS:
I've decided to rework the graphics/menu portions of the Wolfenstein source, right now this is being done in a testbed app first. http://yfrog.com/5bdesmumescreenshot0p
What I'm hoping to do is replace all the software blitted 320x200 graphics with ones better suited to the DS's screen and use the DS's 2D hardware properly.
This will take some time to do but hopefully in the end it will be worth the wait
