Hi all,
Today Ive updated the MAP again:
* Fixed a few cut-off numbers in the Z80 instruction set overview
(http://map.tni.nl/resources/z80instr.php) (no, a JP C, with NC
doesnt take 1 T-state :)).
* Replaced the Div16 16-bits division routine with a faster one by
Flyguille. The speed gain

Flyguille. The speed gain seems quite humble, 3 T-states, but this one can
be unrolled to gain quite some speed.
Another 4 t-states can be saved by replacing
XOR A ; 5 t-states
LD L,A ; 5 t-states
LD H,A ; 5

I have now also added the undocumented Z80 and the R800 instructions to
