I hacked the original Duke3D port to work with the original files, when it was first released. Only thing it did was hound you for missing wav files that weren't present pre-Atomic. Even created a shareware version, so people could play it. (I remember everyone complaining, 'cos I left the PC files in the archive, but at the time, I didn't want to violate the EULA of 3D Realms) Pretty sure I still have it.
