In theory, the Z80 core should work on 32-bit builds now; however, I suspect there is some code that cannot deal with most of the Z80 registers not having a native register so more work will be needed

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.
