Openly licensed source port resources

[elf-alchemist]

Included in many source ports, are resources dedicated towards certain common features. Many of these, however, are potentially restricted by copyright.

The Freedoom project already has a myriad of BSD 3-caluse files, and @nashmuhandes, was able to derive CC0 alternatives for the MBF Helper Dog sprites and sfx.

Boom's digit font remains in the aforementioned legal limbo, and is used all Boom-descendant ports, with Odamex's version being a modification of it.

What other resources could be useful for having such "legally clear" counterparts?

UZDoom's default soundfont (SC-55 Deemster is its proper name I believe) springs to mind, as it's been adopted by at least a few other ports. I think it originally comes from a forum post.

The issue with Deemster's SF2, and well, all SC55/MSGS-soundalike SF2s, is that they are all using proprietary samples from either SC55 hardware, or the MSGS Wavatable itself (GM.DLS).

In Woof, for example, we ship only the DMXOPL instrument bank (MIT license, @sneakernets) and "Tim's 6MB GM" SF2 (GPLv2) for that reason. Thankfully with some of the latest stable releases of FluidSynth, having native support for reading DLS files (i.e. GM.DLS itself) is now a given, so there's a little less to worry about, at least for Windows users, who all have the Wavatable as part of their install (being a Debian user, I had to forage for a copy of it myself 😅)

Tangentially, there's a library called LibADLMIDI, that actually ships with dozens of OPL banks within, so that practice is (legally) dubious at best -- though, of course, I really doubt too many people in reality will really care too much about 90s FM synth banks, it is still not strictly "openly licensed" as we'd need it to be, i.e CC0, CC-BY*, BSD 3-clause, etc, such as how Freedoom is.

it's been adopted by at least a few other ports.

Any examples other than DSDA-Doom? I'm only aware of it as being another adopter of Deemster's SF2.

In all fairness that was the only other example I was aware of (as well as its derivative Nyan Doom). Thanks for the clarification, in any case.
