The RetroDECK DOOM Parser

The Iwad parser will look for any of the CORE DOOM files that could be required to run a DOOM mod in the /retrodeck/roms/doom/ directory.
We have not decided on the entire structure yet under /retrodeck/roms/doom/ but you can follow our efforts on the Discord.

Here is what files it is currently looking for:

IWAD_FILES=("DOOM1.WAD" "DOOM.WAD" "DOOM2.WAD" "DOOM2F.WAD" "DOOM64.WAD" "TNT.WAD"
            "PLUTONIA.WAD" "HERETIC1.WAD" "HERETIC.WAD" "HEXEN.WAD" "HEXDD.WAD"
            "STRIFE0.WAD" "STRIFE1.WAD" "VOICES.WAD" "CHEX.WAD"
            "CHEX3.WAD" "HACX.WAD" "freedoom1.wad" "freedoom2.wad" "freedm.wad"
            "doom_complete.pk3"
            )
