well, there were emulators that allowed you to play PS-One games on it. I think it was called "Bleem" or something, but it actually made the PS-One games look better on the Dreamcast than the actually PlayStation One. My brother had Bleem for Grand Tourismo-x and the shading was better than the PSOne. Try getting a hold of the bleem emulators. They were going to release a whole series, but were put to a halt when Sony sued them and shut them down. You need to get the bleem disc for the actual game you are going to play though... All it does is crack the DRM and load a simple Code-Translator into the memory. But it really does rock!
