EDGE

Anybody know where I can download EDGE? And also, how do I get it to work?
/me is confused with all this 'download, unzip, try to run source port version of game, get some sort of horrendous error such as W_GetNumForName! for ZDoom' nonsense!

Run it like you would DOOM. Type EDGE32, or GLEDGE32, press enter. Nothing fancy.
