It doesn't even show up on the initial list when I run the exe, like it does with the other WADs - it shows the file names and the episode list, and master levels isn't on there
Okay so I found the right file name, turns out you have to call it attack.wad. I had to find that out by looking through the code, which nobody should have to do to use a program. Now the problem just seems to be finding the right WAD, since the one I had threw an error and it seems it couldn't find each map.
Information like that should be contained in the readme file - not everyone knows how to program or look through code, and especially given that I had to do it to actually use the program properly, you shouldn't have to do that.
It still doesn't work, the maps are all inside the master levels WAD. It works if I use the master levels with Doom 2 alone - it shows as another episode and all of the maps work, but if I try to use it with WadSmoosh, it just shows an error and says that it couldn't find the maps.
I tried that, and it seems to have gotten further through the process, but it still doesn't work.
It seems to extract every map to the new maps folder - attack.wad becomes ML_map01.wad, canyon.wad becomes ML_map02.wad, and so on.
It says in the console that it was extracting teeth.wad to ML_map21.wad, and after that it throws an IndexError.
I looked in the pk3 folder where everything seems to be stored before it gets put into the final pk3 file, and every ML_mapXX.wad map is there, except for the final one - ML_map21.wad does not exist in that folder.
I tried changing the filenames of each master levels map so that they were all lowercase, and that had no effect.
I also tried specifying a different order for the master levels in the command line, but that also had no effect.
Since the error was an IndexError and the line it stopped on was:
extract_map(in_wad, in_wad.maps.find('*')[1], out_wad_filename)
I tried changing the 1 to a 0, and it still gave the same error.
I've uploaded the logs, including the error as shown in the console, here: https://pastebin.com/NKy879XW
Then you are doing something wrong, because I have all the needed WADs in my source_wads folder and it works like a charm when I run the .exe. Are you sure you don't have illegal/bootleg copies of your WADs? Or that you didn't edit some unnecessary stuff in the files? These are all the files you need in source_wads:
I have all of the WADs required, they're all in the right place:
I've tried a few different versions of the master levels maps from the internet, and none of them work - it's possible it could be dodgy WADs, but the few that I've tried were all identical down to the file size. I didn't edit anything in the WADs either, I just extracted them with WadExt to get the individual map files, and put those in the source directory.
Again, the original non-extracted WADs work fine with Doom 2, they just don't work with WadSmoosh.
In all the official (ie not pirated) Master Levels releases (with the exception of the PSN version, which can only be attained through either piracy or a great deal of technical effort), the Master Levels are 20 separate WAD files. I always assumed that people running WadSmoosh had legit copies, and I don't support the masterlevels.wad version.
There are two maps included in TEETH.WAD, MAP31 (the express elevator to hell) and MAP32 (bad dream). So WadSmoosh is probably croaking on your handmade version of TEETH.WAD because it doesn't have a MAP32. Though I can't guarantee it won't complain about other stuff if your WADs are all manually extracted from some unsupported thing.
Edit: It also looks like your version of doom.wad doesn't have Episode 4. If you don't actually care about having it in the episode list, you can ignore those errors.
