repos/blastem: z80inst.c annotate

annotate z80inst.c @ 995:2bc27415565b

Fix some stuff with interrupt timing. The change in adjust_int_cycle gets Overdrive working again (vint was not being preferred over hint in some cases). One of the changes seems to have broken Fatal Rewind again, but no other regressions that I can see.

651 103d5cabbe14 Fix flags for rra, rrca, rla and rlca. Fix timing for rr, rrc, rl and rlc when using IX or IY. Fix access to I and R registers (R still needs to be made 7-bit though). Fix flags for ld a, i. The fix for access to I fixes PCM playback in Titan Overdrive and music playback in Crackdown.
