I tried to make this as complete as I could, but there's obviously some files missing. If you have any files, please let me know! Thank you!

I tried to keep things consistent. The more recent source archives came straight from Github (and I don't see any reason why not to keep those, too, so there they are).
The purpose of this is purely historical interest. They are not meant for normal day-to-day use. (It may also help some folks track down bugs, too...)
The existing ZDoom files are still there, as well.

Big thanks to jengelh (aka Hirogen2) who maintained a Sourceforge repository that I nabbed from for a few of the files, and to NeoHippo and Graf Zahl who contributed the bulk of the rest.
