I got the GoG version of the game, upgraded to 1.3a (at least i think i did). Also replaced the cshell.dll with that of moks. The Cshell fixed the loading of menus and so on, but night time and under water still gives completely black screen (except for the starting area). I have tried fiddling with everything i can in the video settings including gamma settings. I tried compatability settings such as xp version 3, color 265 and so on. Has anyone found a solution?
