I done this thread in 2011 but now I think that this game don't need to be ported because in winuae is really fast
on my core I5 I get 39 fps constant at full screen+ gfx high detail
is really smooth, it will not do more because the game is blocked at 39fps, something like the original Doom who was blocked at 35fps
I'm using a special whload version 1.2A by psygore that was never published on whdload site
The game can be played now using ASDW keys+ mouse ( like a pc first person shooter)
in the screenshot you can see is working at 39 fps
if anyone is interested I will upload it a small video of this game running to see how smooth is,just tell me
