Yes it works with other games, i have tried it with Bioshock(i could only get to the level loading screen, it takes probably like an hour to load Welcome to Rapture) and I have tried it with Half Life 2 as well(got a decent FPS with that). Pretty much any game that runs on dx8 or dx9 will work, though the DLL for dx8 is known to be glitchy.
Note that theres also a program called 3d analyze that convinces the program that you have the ability for pixel shader support, but doesnt actually emulate them(so you can actually get the game to start up, some games like bioshock wont start up if you dont have the required graphics). So if you play the game almost everything will be missing. I tried it with Halo, the only thing i could see was glow on plasma weapons, the map, warthog windshields, bullet tracers, etc.
also i think theres a way to make it 1.0(havent tested though) Open the file called SwiftShader(configuration settings) in Notepad, and change the pixelshader version at the top to something like 10(which would be 1.0), then drop it in the same folder you did the DLL's. I cant be bothered to try now though
