Yes, Doom1.wad is the mod, I bundled it with GZDoom for people not-as techsavy as me. And make sure you have OpenGL 3.3 (2014+). If you don't meet those requirements, copy the Doom1.wad out of the folder and get a different SourcePort, or install FreeDoom on android (there is no PC Version) (Download here: https://github.com/mkrupczak3/Freedoom-for-Android/releases), and connect your andoid device to your computer and copy the Doom1.wad file to where the Wad Files are (SD or Internal:\Freedoom\config\wads). and you can now play it (You can use a BT Keyboard or Controller to play too.
