Wed, 20 May 2015 23:34:12 -0700 Michael Pavone Better handling of savestate and debug break events with "uncooperative" games/demos
Wed, 20 May 2015 22:27:51 -0700 Michael Pavone Add some tests for hint timing and fix it properly this time.
Wed, 20 May 2015 19:05:11 -0700 Michael Pavone Upgrade to SDL 2.0 and drop support for the non-OpenGL render path
Wed, 20 May 2015 10:35:03 -0700 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.
Tue, 19 May 2015 23:23:53 -0700 Michael Pavone Small correction to VBLANK flag timing. Fixed some inconsistencies in interrupt timing calculation.
Sun, 17 May 2015 20:03:27 -0700 Michael Pavone 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
Sun, 17 May 2015 19:14:41 -0700 Michael Pavone Call z80_handle_deferred after generating an insruction handler so that instructions like rst work correctly
Sun, 17 May 2015 15:43:20 -0700 Michael Pavone Fix VDP status register PAL bit based on observations of the Titan Overdrive demo
Sun, 17 May 2015 15:41:15 -0700 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 now
Sun, 17 May 2015 15:40:31 -0700 Michael Pavone Fix crash bug in Z80 interpreter
Sat, 16 May 2015 23:08:07 -0700 Michael Pavone Adjust H32 vint slot in response to latest test ROM data
Sat, 16 May 2015 23:04:57 -0700 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, 16 May 2015 22:42:26 -0700 Michael Pavone Fix trans so it compiles again
Thu, 14 May 2015 23:17:55 -0700 Michael Pavone Small horizontal interrupt fixes

Wed, 13 May 2015 23:55:02 -0700 Michael Pavone Fix problem with removing breakpoints
Wed, 13 May 2015 19:19:43 -0700 Michael Pavone Add description of cd register value to vr debugger command
Wed, 13 May 2015 19:13:49 -0700 Michael Pavone Properly print equ for named labels that point outside the cartridge area in disassembler
Wed, 13 May 2015 19:13:15 -0700 Michael Pavone Get save state viewer compiling again
Tue, 12 May 2015 19:14:09 -0700 Michael Pavone Save PC to context struct when syncing Z80 at instruction start. This fixes saving savestates and probably the Z80 debugger as well
Mon, 11 May 2015 20:34:33 -0700 Michael Pavone Remove/comment verbose logging added for tracking down sync bug
Mon, 11 May 2015 20:31:59 -0700 Michael Pavone Tiny cleanup

Mon, 11 May 2015 20:30:13 -0700 Michael Pavone Fixed a missed call to do_sync when updating SR in 68K core
Mon, 11 May 2015 00:28:47 -0700 Michael Pavone Sync fixes and logging to fix more sync issues
Tue, 05 May 2015 08:42:27 -0700 Michael Pavone Added config option to allow specifying a max sync cycle smaller than the end of frame
Mon, 04 May 2015 08:48:10 -0700 Michael Pavone Indentation fixup
Thu, 30 Apr 2015 19:28:18 -0700 Michael Pavone Adjust TH timeout value to take into account the move to master clock cycles

Tue, 28 Apr 2015 19:04:36 -0700 Michael Pavone Fix bug in map_native_address that was breaking some self-modifying code in Gunstar Heroes
Sat, 14 Mar 2015 12:05:03 -0700 Michael Pavone WIP of functions to determine size of x86 instruction to allow patching of arbitrary pieces of code
Wed, 14 Jan 2015 09:38:54 -0800 Michael Pavone Removed hardcoded assumptions in M68K core about which parts of the memory map are RAM
Thu, 08 Jan 2015 23:20:41 -0800 Michael Pavone A couple more indentation fixes
Thu, 08 Jan 2015 21:00:21 -0800 Michael Pavone Moved m68k_save_result to m68k_core.c
Thu, 08 Jan 2015 19:11:56 -0800 Michael Pavone Moved translate_m68k_rte and translate_m68k_reset to m68k_core.c
Thu, 08 Jan 2015 09:36:54 -0800 Michael Pavone Fix indentation that presumably got messed up in a merge
Thu, 08 Jan 2015 07:49:16 +0100 Michael Pavone Merge
Wed, 07 Jan 2015 22:42:35 -0800 Michael Pavone Added ldr and str instructions to gen_arm
Tue, 06 Jan 2015 19:09:00 -0800 Michael Pavone Move detect_region down so that it once again occurs after load_rom since it won't work before the ROM is loaded
Sun, 04 Jan 2015 23:35:55 -0800 Michael Pavone Merge
Sun, 04 Jan 2015 23:21:56 -0800 Michael Pavone Prevent an infinite loop when handling out of bounds addresses in translate_m68k_stream
Sun, 04 Jan 2015 23:05:37 -0800 Michael Pavone Some small synchronization improvements that do not seem to fix anything
Sun, 04 Jan 2015 12:25:33 -0800 Michael Pavone Removed some code that tried to deal with the 68K not using master clocks that is no longer necessary
Sun, 04 Jan 2015 12:24:34 -0800 Michael Pavone Adjusted h40_hsync_cycles so that lines actually take 3420 mclks. Fixed vdp_cycles_next_line to take h40_sync_cycles into account
Sat, 03 Jan 2015 21:54:41 -0800 Michael Pavone Fake busack when Z80 is disabled
Sat, 03 Jan 2015 21:35:23 -0800 Michael Pavone When going directly from reset to busreq, do not allow the Z80 to run
Sat, 03 Jan 2015 21:20:18 -0800 Michael Pavone Added a -r flag to ztestrun that force instruction retranslation to allow a quick sanity test of that feature
Sat, 03 Jan 2015 20:46:45 -0800 Michael Pavone Fix ztestrun
Sat, 03 Jan 2015 20:46:25 -0800 Michael Pavone Fix 68K remove_breakpoint
Sat, 03 Jan 2015 20:20:15 -0800 Michael Pavone Restore emulation of Z80 being locked out of the 68K bus during DMA and the like
Sat, 03 Jan 2015 20:13:51 -0800 Michael Pavone Fix bank area access delay for master clock change
Sat, 03 Jan 2015 18:49:07 -0800 Michael Pavone Restore Z80 interrupt pulse duration and make a small improvement to debug print output
Sat, 03 Jan 2015 18:27:29 -0800 Michael Pavone Removed some obsolete defines
Sat, 03 Jan 2015 18:23:04 -0800 Michael Pavone Made the Z80 core more contained by refactoring some code in blastem.c into z80_to_x86.c
Sat, 03 Jan 2015 16:08:23 -0800 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
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 Michael Pavone Added functions to gen_x86 for saving and restoring callee save registers to better abstract over ABI differences between x86 and x86-64
Fri, 02 Jan 2015 12:04:58 -0800 Michael Pavone Use SZ_PTR instead of SZ_Q in Z80 core for 32-bit compat

Thu, 01 Jan 2015 23:37:24 -0800 Michael Pavone Remove dedicated registers for Z80 bank reg and Z80 bank pointer as they are no longer used
