                    the 64DD. Without your efforts, there's no way that CEN64
                    would have 64DD support.
 
+izy:               For all your optimization work - from the VR4300 to RSP,

 AIO:               Thank you for your RSP/SSE optimizations. It's always nice
                    to see someone else's approaches to vectorizing some of the
                    RSP instructions!
 
 #n64dev:           Thank you to everyone else that's helped out in the past:
