CheckIWAD message

[gmad]

Hello everybody!
I've got Tungsten TX with latest ZDoomZ software. All the times, when I try to run any wad file from list I get message: "CheckIWAD: IWAD tag QKEDOOM.WAD not present". It's message from Quake Doom wad file. With many others is the same...
Could you explain me whats up?

WAD's may all have the same .WAD file extension, but they're different.
IWAD's are stand-alone games made to be played without any games loaded up.
PWAD's, though, are basically mods for Doom games, and usually require an IWAD to run on top of. All you have to do is click the box that says "Active" for PWAD list, pick QKEDOOM.WAD on the PWAD list, and a regular Doom WAD from the IWAD list.
