Beware of latest SS nocd patches
 

Some of them will totally mess up your installed Serious Sam game if you've added a mod. So far..I tried all of them and they
failed. I probably should have installed the
mods after the nocd patch. Still, most of the
latest ones are bunk. I ended up spending an hour getting my Serious Sam up and going again. I've patched SS nocd's before, but the latest ones gave me lots of trouble.Beware!

no, i cant say that, i am using the first ss 1.02 crack postet here and it works fine even with mods
