Sat, 03 Jan 2015 18:23:04 -0800, 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 working
Sat, 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 needed
