Fri, 26 May 2017 19:18:19 -0700 Michael Pavone Avoid splitting m68k_check_cycles_int_latch code across memory chunks since it expects a byte-sized jump offset. Avoid an unnecessary m68k_check_cycles_int_latch for register to register moves
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. VDP FIFO Testing seems to be passing 100% reliably again (was occassionally failing still with the last commit)
Tue, 23 May 2017 23:17:24 -0700 Michael Pavone Fixed regression from VDP sync changes. Direct color DMA demos are now achieving stable sync again

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
Sun, 14 May 2017 12:07:39 -0700 Michael Pavone Fix regression in games that disable the display early like F1 World Championship. Remove debug printf
Sun, 14 May 2017 11:15:56 -0700 Michael Pavone WIP attempt at fixing the minor line -2 glitch in the OD2 Ninja Escape scene
Fri, 12 May 2017 23:34:17 -0700 Michael Pavone Print PATH in build_release script to help debug future build failures
Fri, 12 May 2017 23:33:00 -0700 Michael Pavone Use printf rather than info_message for message about game controller mappings so it does not pop up a modal when not run from a terminal
Thu, 11 May 2017 20:33:31 -0700 Michael Pavone Fix regression in Mode 4 sprite rendering
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 23:41:45 -0700 Michael Pavone Added a region override for the Japanese version of Alien Soldier so it doesn't end up running at 50Hz
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
Fri, 05 May 2017 23:45:45 -0700 Michael Pavone Fix sprite rendering in double resolution interlace mode
Fri, 05 May 2017 23:41:14 -0700 Michael Pavone Decode JMP or JSR with an invalid addressing mode as an invalid instruction

Sat, 29 Apr 2017 16:51:57 -0700 Michael Pavone Initial stab at horizontal border when VDP test register layer selection is in effect for H40. Extended horizontal borders in Titancade scene and ninja escape scene mostly correct now
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.
