Why don't I have a custom title by now?!

This is a string contained in the executables for all Doom engine games, next to the environment variable DMXOPTION and its two recognized substring values, -opl3 and -phase. It is obviously part of the code from the DMX library used Id Software and its licensees.

DMXTRACE, however, is seemingly not documented anywhere. Does anybody know what it is supposed to be, and what it is supposed to do?

Maybe a tracefile parameter of sorts? Try it :-p

It's definitely some kind of debugging option from what I've seen of it.

So, you enabled DMXTRACE there? How is it done?

No clue yet. I just modified the executable to pass all the checks related to the variable modified by DMXTRACE.
Looks like it just prints out extra sound related info during startup.
There is one check that's different then the rest though. I'm not sure what it does.

Edit:
Try "SET DMXTRACE=4096"
