I'd appreciate a list of what should be supported using an EDF file and where should it go in the GZDB interface, since I looked at EDF article in the Eternity wiki and it seems to be the "do-all" format.
edit: was contacted by Altazimuth, help not needed anymore

Although one thing I can say instantly is that adding EDF or DEH from an external file is not going to work, at least most likely.
I've yet to see how GZDB's resources work and if it's possible to add something other than a .wad, .pk3/.pk7 or a directory there.
