OK, I've managed to run the game with megamod but now i stopped with such strange graphics problem:
I have Mode=4 set in ddraw.ini (dx9 fullscreen). When i first tried to run the game i got "D3DX9_42 is missing" error even if i have dx12 installed. So i searched the internet & downloaded just the dll & inserted it to the F2 folder. It helped - the games starts now but, as i've told there is the graphic issue - it's terrible as You can see, just far more worse then with the standard, default rendering (Mode=0). What's going on?
