|Post subject:||Possible Simulator btst.b Issue|
The simulator does not set the Z bit correctly for the following snip of code.
move.l #$7de84d3c, $c0
The 68000 spec indicates that d0 will be used modulo 8 to select the
bit at address $c0 to test. This should be bit 2 of #$7d and the CCR
should have Z=0. The simulator result is Z=1.

Z=0 on IDE68K, will review with HW tomorrow morning.
EDIT: HW has Z=0

Corrected in Sim68K v5.12.4
CODE7.CPP: bit_no was signed long, changed to unsigned long.
