Hello everyone!

If you have a crappy PC like me and couldn't run the package, but still want to run this package in all its glory, here it goes...

Wait, before anything else, a few notes: Maybe someone has already taught this, or taught about running it on other source ports, in any case, it's good to clarify that DOOM Retro currently has support for ID24, which in other words means that you will receive all the effects and screens, this includes the screen between missions (the map showing the character's progress), and you will also have animated skies, as part of the changelog for version 5.6.1 says - "Animated skies defined using the ID24-compatible SKYDEFS lump are now fully supported."

Now let's go... Get your offline installer and use this to unpack it: https://github.com/dscharrer/innoextract
Unpacking is simple, just drag the installer to the innoextract ".exe" file and wait for the process to complete.

Once that's done, separate the files... See the attachment. Create a folder called WADs and put all the files (which are listed in the attachment) inside it.

Download the source port: https://www.doomretro.com/
Source code, bug reports, etc. here: https://github.com/bradharding/doomretro
I suggest creating a folder called DOOM Retro, then download the file into it. Unpack... Get the WADs folder (created previously) and put it inside the DOOM Retro folder.

Run "doomretro.exe", and in the window that opens, select a WAD of your choice... Except "extras.wad", as this is responsible for the rearranged soundtrack, and therefore, is not a game. :)

That's all! ;)

Best regards!

Alright, you like this source-port. Not a GZDoom at least.
Now explain, please, why exactly this one? Why not Woof or DSDA? What will you do when you encounter a PWAD which requiers strictly ID16 or ID18? ID24 currently is needed only for Legacy of Rust (actually it designed for MBF21 but whatever) while older library of the levels is wast -- hundreds and thousands.

The idea here is to provide a source port that is easy to handle and works with all the wads from the DOOM + DOOM II package. You know, not everyone has a PC that meets the minimum requirements of the aforementioned package that runs on the KEX engine, and that requires Windows 10, just to give an example. Those who are on Windows 7, like me, will be fine with DOOM Retro.

As for finding a pwad that uses ID16 or ID18, in that case, there are other source ports for that job. :)
