Setting up GZDoom from scratch is horrible, so I wrapped up this package that has the necessary basics for me to get started on playing modded Doom.
This is mostly a personal resource/backup, but anyone looking to skip the non-sense of setting up GZDoom from scratch will enjoy this. Its got a folder set up to shove mods into, some addons already there, an existing gzdoom.ini with controls/settings/preferences already set up, an autoexec.cfg for crouch/jump allowing on all levels automatically, controls for music volume control ingame with KL, cheats bound to the numpad for convenience. Also includes some tiny addon pk3/wads that I use quite often, few of them even made by me.
Uses a manual low-tech text based mod autoloading procedure that I personally find most convenient, organized and fastest.
