I don't think their is any way they would "make a deal" for sonic or shenmue's saturn beta's. Besides, from what I have gathered, sonic xtreme for saturn (I belive thats what you are refering to), was never able to be played on the system, it never got past the stages where it was strictly pc testing and developing. Supposingly the warp view effect that the game employed was, later in development, found to not be possible on the saturn, so it never made it to the saturn beta stages. I have heard some rumors of a supposed sonic Jam 2, which some people said might have the game in it, seeing as how the effect should be easy to accomplish on the DC, but SJ2 is still just a rumor, so don't get your hopes up. As for what was said about a hardware attachment being used to make shenmue possible on saturn, I would have to say that it has to be true, the polygon count and draw in rate on the video is just not possible on the saturn otherwise.
