Tue, 23 May 2017 23:47:40 -0700 Michael Pavone Go back to resetting the refresh counter after a DMA. Probably not quite correct as it is probably reset on VDP triggered refresh, but this is close enough for now given the general limitations with my refresh code.

Fri, 19 May 2017 22:07:50 -0700 Michael Pavone Add a bit of a hack to HINT start cycle to give correct values in my test ROM and further improve prevelance of CRAM dot noise in Outrunners and OD2
Fri, 19 May 2017 20:54:04 -0700 Michael Pavone Added some code to try and prevent Z80 accesses and refresh cycles from screwing up interrupt latency more than on hardware
Fri, 19 May 2017 20:27:35 -0700 Michael Pavone Fix to M68K interrupt latency for most instructions. Still needs some work for RAW_IMPL instructions besides move

Thu, 11 May 2017 08:01:10 -0700 Michael Pavone Fix regression in mode 4 introduced when advance_output_line was added
Thu, 11 May 2017 07:51:28 -0700 Michael Pavone Fix resampling code to deal with case in which output frequency is greater than the input frequency. Probably could stand to be improved, but at least it doesn't cause the emulator to deadlock
Wed, 10 May 2017 22:06:59 -0700 Michael Pavone Load extra controller mappings from gamecontrollerdb.txt
Wed, 10 May 2017 19:32:13 -0700 Michael Pavone Updated special thanks and version number listed in menu ROM

Mon, 08 May 2017 22:31:28 -0700 Michael Pavone Implemented slow rise time of IO pins set as inputs, but not driven by device. Fixes input in Decap Attack and possibly other games with buggy controller code
Sat, 06 May 2017 00:09:14 -0700 Michael Pavone King of the Monsters worked with my older more inaccurage 6-butotn pad emulation, but does not work with the real thing nor does it work with my current 6-butotn pad emulation. Added a ROM DB entry to force a 3-button pad for this game

Sat, 29 Apr 2017 12:32:50 -0700 Michael Pavone Make internal screenshot functionality completely ignore overscan settings rather than only doing it for the height
Thu, 27 Apr 2017 23:08:49 -0700 Michael Pavone Fixes to sprite phase 2 so that sprite X reads use the exact same slot as on hardware in the case that there are fewer than the max number of sprites on each line. Re-read sprite Y from SAT cache during phase 2 and properly mask the calculated row. Fixes remaining issues with spinning cube scene in Overdrive 2.

Fri, 21 Apr 2017 01:22:52 -0700 Michael Pavone Fairly major rework of how active/passive is handled along with how the V30 mode bit is handled. Allows the vertical border extension trick in Overdrive 2 to work right
Fri, 21 Apr 2017 01:19:40 -0700 Michael Pavone Minor optimization to avoid invalidating translated code when the bank has not actually changed. Makes a nasty edge case in the 68K debugger slightly less severe when dealing with code that uses banking
