Save/restore mapper state in native save states
|

Allow actually saving a save state in more Z80 states. Save busreq/reset state in bus arbiter section for "native" save states
|

Added save states to SMS emulation

New savestates are working. New config file option for selecting format states will be saved in. Mostly complete, needs a little more work before release

Support a couple of bootleg X-in-1 carts

Move I2C EEPROM and NOR Flash functions out of romdb.c into new files
|

Properly release and reacquire framebuffer pointer when switching contexts. Hopefully fixes the LOCKRECT issue some people are seeing with the SDL 2 fallback renderer
|
| Wed, 07 Jun 2017 23:06:14 -0700 |
Michael Pavone |
Initial work to support parallel NOR flash and the Magistr 16

Implemented SMS pause button

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)

Fixed regression from VDP sync changes. Direct color DMA demos are now achieving stable sync again
|

Attempt at improving refresh emulation
|
| Tue, 23 May 2017 21:09:38 -0700 |
Michael Pavone |
Remove HINT_FUDGE and make a small adjustment to how VDP syncs with rest of system instead. Worse results on CRAM dot issue, but much less of a hack
|

Added some code to try and prevent Z80 accesses and refresh cycles from screwing up interrupt latency more than on hardware
|
| 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
|
| Wed, 26 Apr 2017 22:16:12 -0700 |
Michael Pavone |
Small tweak to how SAT cache updates are done. Mostly fixes the rotating cube scene in Overdrive 2
|
| Fri, 21 Apr 2017 23:35:32 -0700 |
Michael Pavone |
Fix a deficiency in the way types were handled in my ternary tree. Fixes in which some paths that were constructed from a template with variables would sometimes get an extra garbage character thrown in
|
| 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
|

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 09:39:54 -0700 |
Michael Pavone |
Fix exit trace mode edge case. Call do_sync if trace mode bit is changed in eori sr
|
| Tue, 28 Mar 2017 00:13:35 -0700 |
Michael Pavone |
Implemented M68K trace mode. Some edge cases/SR update paths still need work
|

Adjust Z80 interrupt pulse duration to match hardware measurements
|

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
