I've played this in the past (GOG version I bought ages ago) and it worked fine on my system. I go back to play it again recently but when it loads up it freezes on the main menu. I can hear the Menu music but can't see the cursor or do anything from there.

Has there been an update or something which broke it? As I say, I played it perfectly fine on this exact system a while back.

What operating system are you using? The last time you played it was it on an older operating system?

Try dgVoodoo, it's a wrapper for old directx (and glide) games to work well in modern OS. To try it you'll need to copy paste 3 of the included files in the main SWAT 3 directory, dgVoodooSetup.exe, D3Dlmm.dll and DDraw.dll then run dgVoodooSetup.exe, choose the desired settings (general and D3D tab in this case) and run the game as usual. The in game resolution settings will no longer affect anything as long as you keep the dgVoodoo files in there but the rest settings will work as always.
