Deeper IWAD Management, Detect IWADs Based on File Headers/Content NOT filenames

[johnglen559]

DoomLauncher's IWAD management is severely limited by the fact that it tracks IWADs based on file name, because of this, you can only keep 1 version of a particular IWAD saved onto DoomLauncher at a time. As a consequence, users can't launch different versions of an IWAD on a whim. There are many IWADs that share the same filename, whether they are from older Doom patches, ripped out of a console port or taken from a newer rerelease, but they are not identical. Please implement deeper IWAD management.

You can simply just rename the file. Just name the file DOOM_v1.666.WAD or whatever naming convention you want. Doom Launcher will give a warning that it doesn't recognize it as an IWAD but you can override it.

The best option might be to leave the IWAD as DOOM.WAD but add it a zip called DOOM_v1.666.zip and add that to Doom Launcher in case a source port cares what the actual filename of the wad is.
