Now how do I add another WAD file to this. Someone needs to play sigil on this.
A disclaimer though - I don't have any experience with Doom modding. I don't know if the behavior of this feature is correct. All it does is it loads the PWAD by passing the "-file" argument to the game's main function.
I've been playing around with the version that was up yesterday. I managed to get my DOOM Resume running in the PDF https://github.com/adamrmelnyk/thisResumeRunsDoom.
Is it playable.... eh? that's another matter. I think I'd need to modify it a bunch. Right now the doors don't seem to open when playing the PDF. I could just remove them all though.
