Sun, 24 Apr 2016 02:19:48 -0700 Michael Pavone Half assed, prefetch based open bus value emulation. Gets BlastEm up to 119/122 in VDP FIFO Testing
Sat, 23 Apr 2016 18:14:01 -0700 Michael Pavone Disable refresh emulation with some ifdefs for now as it currently is not accurate enough to actually improve overall accuracy/compatibility and in fact makes things that work right on real hardware break
Sat, 23 Apr 2016 01:08:43 -0700 Michael Pavone Fixed loading of SMD format ROMs
Thu, 21 Apr 2016 22:08:26 -0700 Michael Pavone Move mouse mode and capture state to emulation context so it persists properly when switching between the menu and the game
Sun, 17 Apr 2016 23:50:41 -0700 Michael Pavone Save State menu option is now fully functional. Load state sort of works, but is mostly broken.
Fri, 15 Apr 2016 23:57:50 -0700 Michael Pavone Save state menu WIP
Fri, 15 Apr 2016 20:39:26 -0700 Michael Pavone Saving the save directory in the rom_info struct didn't make sense. It should be in the console context.
Fri, 15 Apr 2016 18:29:39 -0700 Michael Pavone Switch to storing SRAM/EEPROM and save states in a per-game directory rather than next to the ROM (for SRAM/EEPROM) or in the current working directory (for save states)
Tue, 12 Apr 2016 21:38:24 -0700 Michael Pavone Remove the int number argument to vdp_int_ack since it is no longer used

Wed, 04 Nov 2015 23:01:15 -0800 Michael Pavone Default to fullscreen on Android since windowed mode does not make sense there

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, 04 Jan 2015 23:35:55 -0800 Michael Pavone Merge
Sun, 04 Jan 2015 23:05:37 -0800 Michael Pavone Some small synchronization improvements that do not seem to fix anything

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
Thu, 01 Jan 2015 22:52:18 -0800 Michael Pavone Adjust 68K sync cycle when mclk_target gets adjusted
Thu, 01 Jan 2015 22:18:32 -0800 Michael Pavone Add the 3 cycle delay back in to Z80 bank area access

Mon, 24 Feb 2014 01:30:16 -0800 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.
Tue, 18 Feb 2014 21:37:31 -0800 Michael Pavone Initial work on the x86-32 target
Thu, 13 Feb 2014 00:10:36 -0800 Mike Pavone Properly sync hardware when frame end is reached during DMA

Sun, 09 Feb 2014 17:16:55 -0800 Mike Pavone Added step and step-over debugger commands. step-over is like next except it doesn't follow conditional branches to lower addresses. This makes it useful for advancing to the end of a loop. Also fixed a bug in next introduced by the refactor.

Sun, 09 Feb 2014 10:29:29 -0800 Mike Pavone Properly handle dbcc, rtr and rte in the debugger next command

Mon, 03 Feb 2014 09:18:10 -0800 Michael Pavone Initial attempt at emulating extended bank area access delays when 68K bus is busy with VDP stuff. Also emulate the extra delay on the second access of a word-wide read to the bank area. Needs work as it seems to break stuff.
Mon, 06 Jan 2014 22:54:05 -0800 Michael Pavone The local clone on my laptop got messed up and some changes had not been pushed. This commit represents the status of the working copy from that clone. It unfortunately contains some changes that I did not intend to commit yet, but this seems like the best option at the moment.
