About ZDL4

ZDL4 is a launcher for Doom engine source ports. Pick a port, pick a game, add PWADs, patches or unpacked mod folders on top, and launch.
Profiles keep each setup together with its own port config, saves and demo recordings. ZDL4 can also fetch and install supported source ports for you, among them GZDoom, Zandronum, DSDA-Doom, Woof!, Nugget Doom, Chocolate Doom and Crispy Doom.
ZDL4 is only the launcher. The source port and the game data are yours to get separately.
