I had the same issues on Win8 x64. The ddraw.dll fixes made it possible to play but i had always scrolling lags and sometimes issues with the menus (mostly saving). After a lot of try&error i've found a way were these issues are gone (well main menu isn't centered because of static resolution, but i think thats no real problem).
1. Compatibility mode for Game.exe (only 16bit colours and admin)
2. sun.ini resolution 1362x740 (max screen is 1366x768 but removing some pixels at the borders solved scrolling lag)
3. used http://bitpatch.com/ddwrapper.html with NoVideoMemory = 1 and rest default
4. start Game.exe with -win for window mode
i've played some games with saving and so on without any issue...
