I think what Alex is asking for is enough information to write your own
3d engine.  Personally I would love to port my own engine but the Gs
functions just do not cut it.  I think the Gs lib primitives are not
primitive enough.  :-)

I would also like to hit the bare metal better with copros.  Can we get
a list of copro 2 (GPU i think) registers and opcodes?  Also a list of
the parameters for the break opcode would be handy.  I have a feeling we
are working quite a way away from the real hardware.

While I'm here a quick question about the manuals.  I guess they were a
direct translation from the Kanji version.  As the Yaroze uses function
calls from the full libraries why were the library reference
descriptions not taken from the full Professional English language
library reference manuals?

I also understand that the manuals are begin rewritten by an adult.  Can
we expect to get a complementary version in the post when they are
complete?

Regards

Jim
