Nintendo's emulator on Revolution for the old games...

Since Nintendo designed the CPU's used in all of the systems (and I assume they get coded in software first before being brought to silicon), won't their emulators be 100% compatible with the the games, where others who have made emulators have had to reverse engineer everything and just kind of guess at what everything should be?
 
nintendo didn't design thier cpus

the NES had: 8-bit 6502 NMOS
SNES: 16-bit 65816
N64: 64-bit R4300i RISC with another 64bit RISC co-proc which also handled graphics (prolly a semi custom chip here)
Gamecube: Power PC derivative, with a ATI graphics chip (not really ATI I forgot who built it really)

Wouldn't they have access to the designs though? Or would they need to get each of the respective companies to build the code for each piece of hardware for them?
 
yeah they ahve acess to the designs but most of those chips are so old that everyone has acess to that same info.

The n64 design is still basically under NDA. I recall an article saying any information on the n64 is severely protected (a journalist was at Nintendo's HQ covering the Gamecube launch). Kinda odd really, but whatever. I guess rambus might sue them 😉
