It's a wonderful creation but i can't make it work.. I have an original Eneba copy of Doom 2 activated on Steam. I open the game dragging the WAD on the executable gzdoom.exe and i select "Doom2:Hell on Earth" from the menu.
Starting the level I immediately find important graphic glitches in the sky which I can't attach because the windows capture function only gives me the Doom 2 home screen.
Entering the hole at the beginning the game crashes and gives me back to the desktop.
There is no readme.txt in the installation file so I had to improvise.
Various other WADS for Doom 2 works.
