Is this possible? Both require a modified .exe it seems so how should one go one with this? Also, are there a lot of things that got fixed in the unofficial because if it's just a few things I rather prefer the fix to avoid stretch in widescreen.

Edit: I just read the readme, I might have misunderstood that patch. All it does is adding experimental real-time shadows or what?

I don't know that too. When I saw modified exes, I chose widescreen patch :P I haven't heard this game being buggy or anything, but better aspect ratio in widescreen is always welcome ;-)

Well, this was welcoming. I threw in the .dll that came with the zip of the widescreen patch but I switched the exe to the shadow patch instead. Now I've the shadow patch and correct aspect ratio but real-time shadows aren't working. Still, I added the patch because apparently it was suppose to fix some bugs that wasn't addressed in the latest official update so it can't hurt try with it, I hope. :P
