Most Advanced DOS Source Port?

[Trusty McLegit]

I know BOOM was a big thing on DOS, but what was (or is) the most technically advanced source port that can run on DOS?

Vavoom.

It's got colored dynamic lightmaps in a software renderer, supports models, (also supporting NORMALS on the models), Strife, and some (older) zdoom mods.

Wow, this is pretty advanced! I'll need to adjust dosbox to get it running just right, but this made me think, what is the most technically advanced game in general that can run in DOS? I know there were a number of fairly impressive tech demos, but I'm looking for the most advanced piece of software you can actually interact with and control that runs in DOS? Any Ideas?

Please define "the most technically advanced game" Tomb Raider? Quake? Blood? Carmageddon? Chasm: The Rift? Lots of them.

If i'm not wrong you developed a reverse engineered version of Chasm...
I forgot about Vavoom. There's a new version of MBF (2.04 released @vogons, has Killough's approval), a more recent Eternity version by hail-to-the-rayzen also released @vogons (i never managed to run it on dosbox, he was the original creator of ZDoom LE BTW) and of course there was a DOS version of Doom Legacy.

I gave up at the very beginning Doing this by hand is too long and boring process.
Automated tools for 16-bit protected mode DOS binaries are almost non existent.
Writing a decompiler for this long dead platform is completely out of my interest.

I thought Chasm was a 32-bit protected mode DOS program, curious.

Sadly it's not. That's because it was written in Borland Pascal with some inline assembly.
Curiously enough it uses fixed point arithmetic only, i.e. should run without FPU.

I used Borland C++ and Turbo C++ back in the day, i remember that 'carcinogenic code' with near and far pointers. Then i moved to DJGPP and Dev-C++ later but sadly many years without coding since then.

Engoo used to target DOS until it had a mysterious crash bug at some point. It should still compile with DJGPP at least...

Is that one you or is that somebody else then?

No, this guy did much more than me. Glad that someone is working on reconstruction of this hidden gem.
