I've been searching around for new PWads to use with DE and obviously the first issue is what port of Doom/Heretic the PWad was created for or is compatible with. I've noticed that many PWads are surprisingly old but some still work even though they don't mention DE by name.
One common phrase I've seen often is:
Advanced engine needed : Limit-Removing Port
Q1: Can someone explain to me what a "Limit-Removing Port" is? and am I correct guessing that DE qualifies as one?
Q2: I was a bit surprised at the number of ports there are (or rather have been, no idea how many are left and active).
Can anyone tell me if DE is compatible to any degree with other ports, in terms of running a typical PWad? (I do understand that some PWads may use advanced features and may not work while others might, I'm just looking for a wide-angle guess!)
and Q3: Can anyone say how many are still active today? (referring to Heretic not only the Doom engine alone)
Many thanks for any information in advance!
