doomlegacy alpha3 for windows, runs heretic pretty well, in opengl. VERY WELL, as a matter of fact. Unfortunately, my favorite, graphic enhancing feature, that helps Legacy leave the "pack" behind, as far as visuals...is sorely missing. Recent dynamic lighting was added, so thats a major plus, but .. Will we ever have CORONAS!
I have plans to fix coronas for everything, but is not a high priority item.
Right now it has to be done by hand, customized for the sprite.
For modified sprites, the corona is in the wrong location.
When I can fix this so the correct corona location is dynamically detected, then it will be fixed for Heretic too.
