You need to run in an non interlaced mode to be able to run ddraw in windows 7, just like it says on the ultimarc website! Try setting your windows desktop to 640x288, and ddraw will work fine! Not sure if you read the hyperspin forum or not, but running at that resolution with hyperspin messes up how it looks, so i just use d3d instead, everything looks good to me this way. I'm 24, I didn't grow up in arcades during the "golden age", i just like playing arcade games, and at times I prefer 2d over 3d, and with d3d I get "smoother" graphics, but they still have the "arcade" feel on my wells gardner 25k7191, but just a little bit cleaner and not as many jaggies/blocks as what ddraw gives me. Now i realize this isn't the "true" arcade feel, but it looks good to me and all of my friends/wife versus a true ddraw picture, plus i play street fighter/shooters/neo geo/cps stuff more than golden age anyways, so i just stick to d3d!
