Some wads just doesn't work

For example Eternal Doom IV. When I run them, the game starts on original Doom 2 first level. Why is that?
Because you do not read the text files that accompany these wads and which say what levels are replaced.
Eternal Doom IV starts on MAP08, not on MAP01. Since maps 01 to 07 are not replaced, the normal Doom II levels are still there instead. There are only seven new levels in ED4, which are maps 08, 09, 10, 11, 12, 13, and 27. There is a MAPINFO lump so you'll just directly from map 13 to map 27, but they forgot to make the game start at map 08. You can do that yourself with the idclev cheat, the map console command, or the -warp command line parameter, etc.
In any case, this is not a bug.
