Sun, 16 Apr 2017 16:40:04 -0700 Michael Pavone Initial work on handling the 128KB VRAM mode bit and some basic prep work for VDP test register support
Sat, 15 Apr 2017 21:45:19 -0700 Michael Pavone Fix copy pasta error in handling of Z80 VDP port reads. HV counter reads are not illegal writes =P. Fixes immediate exit in Overdrive II, though other problems remain
Thu, 30 Mar 2017 23:59:57 -0700 Michael Pavone YM2612 should also be reset on system soft reset
Thu, 30 Mar 2017 23:57:30 -0700 Michael Pavone Reset YM2612 whenver the Z80 is reset. Fixes issue with stuck notes in Fantastic Dizzy and Kid Chameleon

Tue, 28 Mar 2017 00:13:35 -0700 Michael Pavone Implemented M68K trace mode. Some edge cases/SR update paths still need work

Sun, 19 Mar 2017 11:14:34 -0700 Michael Pavone Minor fix to hacky refresh emulation code to more closely match my intent
Sat, 18 Mar 2017 23:18:37 -0700 Michael Pavone Basic refresh emulation that doesn't break direct color DMA demos. Fixes sound after entering pause menu in Pacman 2: The New Adventures
Sat, 18 Mar 2017 17:09:14 -0700 Michael Pavone Remove hacky post-DMA delay add proper pre-DMA delay based on logic analyzer capture. 512 color screen is a bit messed up but mostly works. Needs investigation

Wed, 01 Feb 2017 21:19:35 -0800 Michael Pavone Basic implementation of serial IO registers, but without actual serial IO support. Needed to run a certain software check cartridge that is floating around.
Fri, 27 Jan 2017 21:27:37 -0800 Michael Pavone Implement soft reset in Genesis mode
Thu, 26 Jan 2017 20:07:17 -0800 Michael Pavone Added config file option to specify that RAM should be randomly initialized. Moved default_region inside a new "system" parent node in config
