There is a port called FastDoom that could serve as inspiration for achieving better performance. https://github.com/viti95/FastDoom https://github.com/viti95/

  The SFX Doom is a lot of assembly. I think the official Lion port of Doom to the Mac uses a lot of assembly too. (Heck, plenty of it in the original.) 68K isn't hard to write in, and I think any fast implementation on hardware of this spec won't be able to avoid it.

  When porting to SerenityOS, Andreas used a Doom flavor that required very few platform-specific changes to make it run: https://github.com/ozkl/doomgeneric https://github.com/ozkl/doomgeneric

  A third renderer that exists is the assembly for the official Jaguar port. I think Carmack wrote it? It's staged, like a really old C compiler, because the Jaguar's faster processors could only execute programs from a tiny scratchpad memory. https://github.com/Arc0re/jaguardoom/blob/master/r_phase1.gas https://github.com/Arc0re/jaguardoom/blob/master/r_phase1.ga... I think Rebecca Heineman ported this back to C for the official 3DO port. https://github.com/Olde-Skuul/doom3do/blob/master/source/phase1.c https://github.com/Olde-Skuul/doom3do/blob/master/source/pha...

    And she did it in a few months! No time to get music working so someone at Panasonic got a band together and recorded a garage band redbook version.
