Sun, 06 Aug 2017 00:06:36 -0700 Michael Pavone WIP - New savestate format

Mon, 02 Jan 2017 23:35:40 -0800 Michael Pavone Invalidate translated code on a cartridge bank change in SMS mode. Fix handling of bank 0
Wed, 28 Dec 2016 20:39:27 -0800 Michael Pavone Remove memory map assumptions from Z80 core and move a little bit of logic to the generic backend.c so it can be shared between CPU cores
Thu, 22 Dec 2016 19:51:25 -0800 Michael Pavone Initial support for Genesis/Megadrive PBC mode. VDP still needs Mode 4 to be useful.
Thu, 22 Dec 2016 10:51:33 -0800 Michael Pavone More cleanup in preparation for SMS/Mark III support

Wed, 27 Jul 2016 22:46:22 -0700 Michael Pavone Change cycle tracking code for Z80 core to only use a single register. Store low 7 bits of R in a reg and increment it appropriately.
Wed, 20 Apr 2016 23:19:13 -0700 Michael Pavone Fix bug in Z80 rrd implementation. This fixes the annoying high pitched wine in Afterburner II.

Wed, 29 Jul 2015 00:03:36 -0700 Michael Pavone Added support for an IO memory map in Z80 core
Mon, 25 May 2015 18:56:22 -0700 Michael Pavone Add a define in both the source and Makefile for enabling logging of z80 instruction address/cycle counts. Fix Z80 in/out instructions to eliminate assumptions about which registers are stored in native regs. Fix read_16 to not corrupt the low byte when the read has to call into a C function.
Sun, 04 Jan 2015 23:35:55 -0800 Michael Pavone Merge
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
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
Thu, 01 Jan 2015 22:18:32 -0800 Michael Pavone Add the 3 cycle delay back in to Z80 bank area access

Tue, 30 Apr 2013 20:36:15 -0700 Mike Pavone Add a second context pointer to m68k_context so that try_fifo_write can still have easy access to the VDP. Handle writes to Z80 code addresses from the 68K.
Mon, 29 Apr 2013 21:46:48 -0700 Mike Pavone Implement retranslating code when written to. Possibly broken, need to fix some other bugs before a proper test.
