Yes, I confirm that Jessica has gotten to this
We will release a
public beta when ALL (or ALMOST all) actors are done the closest possible way we can afford without rewriting entire (G)ZDoom

The beta will bear a proud number of 4.3 .
However, we will surely need some more assistance. Mapping (=
recreating) and playtesting are the most notable things that can never be too much.
(Some on-topic blabber:)
There are a few features that would be nice to implement but which are impossibly hacky without
this. And I failed to compile (G)ZDoom on Windows while following the instructions on Wiki, so I can't even beta-test this code I submitted

.
I'll have another try in a few days, but if there is anyone able to test this code and/or correct/improve it, it would be great too.
