Their is almost no differences between the Yaroze hardware and the "infamous" Blue debug PlayStations. The territorial lockout is different and that is located in the CD rom controller. The MPEG (MDEC) engine is part of the CPU (as is the serial I/O) and is indeed in the Yaroze hardware. I believe the Yaroze libraries do not include any functions for it..... for a variety of reasons. As the Yaroze does not boot CDR's, no streaming functions off the CD were included. And yes I know their are ways to hack the console to run CDR's, but let's not go there :) The bottom line is that the Yaroze hardware is essentially the same as the blue debugs. All hardware functions availible on the blue debugs are possible on Yaroze with exception to the CDR lockout.
