I think I have the solution. My problem was similar, but I also had a dialog box pop up complaining about Xaudio2.cpp not being found and some stuff.
All I had to do was run the directx updater thingy. Prototype seems to have this problem, too. I found this fix as a fix for Prototype, but it works just fine for SSF. Both XP Pro x86 and 7 Ultimate x64 were fixed by the same updater, too. (I just built a new computer, and I'm dualbooting with both OSes.)

They said Saturn emulation could never be done. Yeah right. Fighters Megamix and Daytona USA CCE run great after I did the maximum compatibility option. Daytona's got background flicker, but you don't notice that when you're racing! Anyway, I forgot how crappy Daytona looks compared to the direct3d patched Daytona USA Deluxe for the PC. Oh well, it's still good times
I've got to try more of my games later!
