Changes :
I suppose I should start calling these nightlies, heh. blargg went ahead and verified every last possible edge case with regards to the S-CPU MUL / DIV registers. It uncovered a few errors in my implementation, which have since been corrected. The design used now should be a direct reflection of the hardware implementation: no actual multiplication, no actual division, and no variable-length bit-shifting.
We also spent about eight hours straight hammering away at the S-SMP test register. We have a partial understanding of TEST.d3 and TEST.d0, and a complete understanding of the other six bits. All of this has been implemented as well.
Lastly, snesreader gets a tiny update to fix Test Drive II, which broke due to a slight regression when porting the mapping code to XML.
