@James, sideline to this thread: Sony spend a lot of time on research and development of processors, thus the data will not be available. This goes for all chip designers, and yes you can never have the access to those diagrams either. Am still waiting for the socialist movements world to engineer even the oldest computer processor known. A question to you, out of interest: How do you tell the difference between a npn and pnp transistors and how would you determine the base, collector and emitter of a simple transistor. Once you determine the 3 items, how would they connect to a voltage source for e.g. switching a current or voltage source. This is like really really old school. No google pls. :-) Rgds. 2011/12/5 James Nzomo <kazikubwa@gmail.com>
@Steve lol. The barriers are guan.
He will have a veeeeery difficult time prototyping with the player's surfacemount μCs & other components. Secondly Sony will most definitely use their own custom μCs that have very little if any useful supporting documentation available to the public. Couple all that with a possible steep learning curve and the threat of legal action<http://en.wikipedia.org/wiki/Sony_Computer_Entertainment_America_v._George_Hotz> and it will be clear that all that trouble just to play excluded formats on the HT will not be worth it.
