Wed, 20 May 2015 19:05:11 -0700, by Michael Pavone
Update vscroll latch implementation to be more in line with what Eke-Eke has observed. Revert the change to vdp_cycles_to_line because it breaks hints on line 0. H-Int timing is still a little messed up, but the previous change made things worse.
Wed, 20 May 2015 10:35:03 -0700, by Michael Pavone

Fix crash bug in Z80 interpreter
Sun, 17 May 2015 15:40:31 -0700, by Michael Pavone
Adjust H32 vint slot in response to latest test ROM data
Sat, 16 May 2015 23:08:07 -0700, by Michael Pavone
First pass at emulating a vscroll latch. Titan's Overdrive demo seems to depend on the scroll value being latched early in the line before the HINT gets a chance to change it

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
Fri, 02 Jan 2015 13:47:34 -0800, by Michael Pavone

Wed, 18 Jun 2014 16:30:19 -0700, by Michael Pavone
Partially working switch to having a vcounter and hslot counter in the context rather than trying to derive them from the cycle count. This should allow for more accurate handling of mid screen mode switches. Interrupt timing is broken currently though
Tue, 17 Jun 2014 19:01:01 -0700, by Michael Pavone
Fix a few values reported by the vr debugger command. Add DMA registers to vr debugger command. Fix horizontal interrupt bug. Slightly more accurate (but still broken) handling of switches between H32 and H40 modes.
Mon, 16 Jun 2014 19:13:28 -0700, by Michael Pavone
Fix handling of code writes for Z80 core. This seems to get things close to being back to where they were before the big refactor that broke the Z80 core. Some problems remain. Notably the sound driver in Sonic 2 is still quite broken.

Sun, 02 Mar 2014 14:46:55 -0800, by Michael Pavone
Refactor gen_x86 to use an interface more like gen_arm and to remove the need for the caller to decide whether an 8-bit or 32-bit displacement is needed in the rdisp functions. Update m68k_to_x86 to use the new version of the gen_x86 functions and do some minor refactoring there in the process
Sun, 02 Mar 2014 14:45:36 -0800, by Michael Pavone

Fix x86_rrindex_sizedir. Pass the correct scale to mov_rindexr in gen_mem_fun. BlastEm now sort of works on OS X. Runs reliably from lldb, but only intermittently from the shell

blastem builds and almost works on OS X now
Tue, 17 Jun 2014 01:50:29 -0400, by Mike Pavone
Use a typedef code_ptr in place of uint8_t * in 68K core to better support host instruction sets with different instruction word sizes. Make x86_68k_options contain a cpu_options so that gen_mem_fun can eventually be shared with the Z80 core.

Generate get_sr, set_sr and set_ccr at runtime so they can respect the flag_regs setting
Tue, 18 Feb 2014 20:32:10 -0800, by Michael Pavone
Make references to flags in the M68K core respect the flag_regs options array so that flags can be moved out of registers for the 32-bit port. set/get ccr/sr still need to be updated to support this, but everything else should be done.
Mon, 17 Feb 2014 19:58:37 -0800, by Michael Pavone
