when you say "reverse-engineering", do you mean by using some of the old
asic documents you retrieved some time ago (and following the different
connections/combinations of each signal to determine the "pseudo" code),
or by working on a decapped chip ?

This indeed came from documents that I have and from puzzling out the
connections and logic gates shown there. So there's always the small
possibility that these documents differ from what was actually put into
silicon. But I don't know how to reverse-engineer from a decapped chip.

I thought the documents you found were about the STE GST/MCU ; seems I misread :(

Jorge/"ijor" on knows how to do that:
<>. He's also the one
who found out that the C025912-38 MMU is a Ricoh gate array.

Yes, I closely followed these thread too, especially the ones on the mmu / shifter regarding the wake up states :)
