[REL/FINAL] GZDoom-GPL 2.4 - now with software renderer

Projects that have specifically been abandoned or considered "dead" get moved here, so people will quit bumping them. If your project has wound up here and it should not be, contact a moderator to have it moved back to the land of the living.

There are other software that support (at least some of) these tags, as noted there. Might be worth more investigation to see how they implemented it.

LOOP_BIDI could be implemented by "compositing" the sound with its reverse, and looping the result.

Once the OPL emulation works again, the branch can be merged.

There's a small problem here: MUSLIB is used as the mediator between the high level code and the OPL cores. The high level code expects MUSLIB to be there so the functionality has to be very carefully transitioned to new code. You can't just rip everything out and rebuild it, you have to replace it piece by piece to make it work. Otherwise you run into so many walls that the end result would most likely be broken.
It would be easier if you just could dump a MIDI file player in there but with ZDoom supporting 5 different MIDI file formats and some native OPL formats this is going to be tricky.

The problem with Muslib is a bit annoying: There is enough code out there but it's all strict GPL, meaning that it cannot be used in a gradual refactoring without some of the zealots crying foul.

I actually don't see a huge problem with this. Nash's GZDoom-GPL can be used as a base for that, and it seems to be generally accepted for what it is. Once you're ready - drop the code in and run.

As was foretold 2 years ago...

and with that, this project can be graveyarded. :D
