I'm not sure how AGES feel about accepting fan contributions. If they had, they'd likely have a much more refined spin dash programmed that's for sure. Concerning R, I guess it depends on choice of conversion. They might just use a Saturn emulation if they have advanced enough, though the PC port is likely the most accessible, and hopefully it would be smoother to convert onto newer systems than the Gamecube and PS2. We'll have to see how any of their alleged planned Saturn titles are released first.
