qzdl VS MultiMC5

ZDL (ZDoom Launcher) simplifies the process somewhat: ZDL Github. You can move the ZDL exe file into the same directory as GZDoom.

if you do use ZDL there is a linux version over here i think that needs you to use this standalone/portable gzdoom rather than the flatpak or ZDL cant find gzdoom to launch properly.

I'm trying to configure ZDL to launch the Doom done Quick demos through a ZDL file, but I can't get it to work. I'm using PrBoom-plus. If I run it through the command line, it works fine, but not through ZDL with the same options.

Check out https://zdoom.org/wiki/ZDL and then download ZDL from the first link (https://github.com/lcferrum/qzdl/releases/tag/3-1.1).

Get a launcher. I use ZDL myself and it's just fine. https://github.com/lcferrum/qzdl/releases/tag/3-1.1

MutliMC: https://multimc.org/

probably not with an unmodded version. if you want to use a different launcher for whatever reason i would recommend taking a look at MultiMC (https://multimc.org/) its a free multi platform launcher that lets you log in with both mojang and microsoft accounts and lets you have multiple installations of minecraft in the same launcher (very nice with modpacks so that you don’t have to keep messing around in the mods folder) its works on macos, linux and windows. so if you are using the old launcher because the new one doesn’t work on your current operating system this launcher might just work!

See some screenshots here: https://multimc.org/

I use Multi MC for addons and mods. https://multimc.org/ might make it easier.

Honestly Just get GDlauncher or MultiMC , both eliminate the need for the overwolf FTB hybrid. GDlauncher is pretty straight forward , I dont personally use MultiMC but alot of people do so theres bound to be guides on yt .

MultiMC is what you're looking for. It tries to retain compatibility with very old MC.
