Dear All,
I'm currently trying to reverse engineer an 2002 vintage Yamaha chip that is similar - but not exactly the same - to the AICA ARM7 chip, and I am hoping that Yamaha reused alot of the AICA design in this particular chip. Given that you guys understand the Dreamcast inside out, I thought that you might be able to point me in the right direction. I've tried to search for this information but not found it anywhere; hence the direct questions.
Firstly : does the DC AICA actually load up firmware from (e.g.) onboard flash when it starts up? If so, does anybody have a binary image of that firmware? Have people dissassembled it, or have
Secondly : does anybody know what the memory map of the AICA is, in particular including any of the IO ports?
Best regards,
..pika..
