Neo Geo Doom ports prove the impossible was a dare

Hackers have pushed past the once-described “impossible” barrier by porting Doom to stock Neo Geo hardware via two projects, Doom64KB and Doom-NG. Doom64KB uses a proto frame buffer from the fix layer to render Doom maps at low color, while Doom-NG applies a sprite-based renderer that stacks walls and objects to simulate 3D views. The results are recognizable Doom with a stripey, low-color look and decent frame rates, but with clear graphical compromises and still-missing gameplay elements like enemy AI, music, and weapon handling.
