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 demoSun, 17 May 2015 20:03:27 -0700, by Michael Pavone

Don't overwrite an instruction offset mapping with an extension word value. I really need the ability for a word to be mapped to more than one instruction, but this will be more correct for nowSun, 17 May 2015 15:41:15 -0700, by Michael Pavone

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 workingSat, 03 Jan 2015 16:08:23 -0800, by 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 neededFri, 02 Jan 2015 13:47:34 -0800, by Michael Pavone
