Hopefully this isn't the documentation on the 7654 SuperH-2 that you're talking about. That's freely available from Hitachi themselves. :nod:
As cool as Saturn stuff is, there's so much of it. We need more Mega Drive family stuff D: Can't wait to see what it is though, I'd put towards it if I didn't have AP tests to pay for
We already have: * Official Hitachi SH-1/SH-2 Programming Manual * Official Hitachi SH7604 Hardware Manual
The SH-2s in 32X and Saturn are SH7095, and I have yet to see docs of them, pinout would be nice to have...
