Help - launch wad files?

So I want to try Hexen and a WAD file I found with cool weapon mods.
I tried Vavoom 1.31 but it doesn't have a menu to select wads.. it just loads Hexen right away...
What's the best app to use for this? I tried doomsday but it had problems so I couldn't even use it..

First of all, we need to know what these weapon mods are. They may not be compatible with vavoom or doomsday.

Most weapon mods are compatible with (G)ZDoom or Zandronum only.

This is how you can launch wads from the command line:

sourceport_filename -iwad iwad_filename -file pwad_filename(s) gameplay_mod_filename(s)

For example:

zdoom -iwad doom2.wad -file av.wad bdv20b.pk3

Execute the command from the sourceport's directory. All wad/pk3 files you're trying to launch should be in that directory too.

You can also .....

-iwad "D:/Folder/Subfolder/StuffAndThings/Yaymywad.wad" -file "D:/Folder/Subfolder/StuffAndThings/Yaymywad.wad"
