Make sure z80_save_reg does nothing when there is no register in the reg field of the instruction. This fixes a bug that corrupted SP in the MDEM 2011 demo

All cycle counters are now based off the master clock. This seems to have messed up Z80 interrupt timing (music in Sonic 2 is too slow for instance), but things are generally working
|
Fri, 02 Jan 2015 13:47:34 -0800 |
Michael Pavone |
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
|
Fri, 02 Jan 2015 13:14:09 -0800 |

Added functions to gen_x86 for saving and restoring callee save registers to better abstract over ABI differences between x86 and x86-64

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.
