2019-01-20Implement serialization/deserialization in libretro buildMike Pavone
2019-01-20Fixed the most glaring issues in libretro buildMike Pavone
2018-11-19Removed old VDP debug functionalityMichael Pavone
2018-11-16Small cleanup of vdp_context struct layout and removal of separately ↵Michael Pavone
allocated buffers
2018-11-11Make sure M68K sync and target cycles are updated after loading a savestate. ↵Mike Pavone
Fixes an issue in which loading a savestate would result in things being unresponsive until emulation cycle caught up to whatever the pre-state load sync cycle was
2018-11-04WIP new VDP plane debug view and support for detached VDP debug views generallyMichael Pavone
2018-08-14Added J-Cart supportMichael Pavone
2018-07-06Update controller config when changed in UI without restartMichael Pavone
2018-06-28Fix a number of other memory errors (mostly leaks again) identified by valgrindMichael Pavone

2018-05-01Release capture of mouse and keyboard when entering UIMichael Pavone

constants to minimize latency without leading to dropouts

2018-03-30Randomize soft reset timing and fix silly bug that was accidentally clearing ↵Michael Pavone
IO state on soft reset

dynamic audio rate control
2018-03-28Small cleanup to audio interface between emulation code and renderer backendMichael Pavone
2018-03-24MergeMichael Pavone
--HG-- branch : nuklear_ui
2018-01-31Made the NOR flash emulation a bit more flexible, but not yet flexible ↵Michael Pavone
enough to properly support the flash chip in the MegaWiFi cart
2017-11-24Fix genesis save state loading via Nuklear UI, sms probably still needs workMichael Pavone
--HG-- branch : nuklear_ui
2017-11-24Refactored save slot related logic to reduce duplication and allow reuse in ↵Michael Pavone
new UI. Get state loading/saving mostly working in new UI --HG-- branch : nuklear_ui
2017-10-19Implemented Z80 IM 2 and attempted correct intack cycle delayMichael Pavone
2017-08-29Make initial bank register state stored in bank_regs match what is put in to ↵Michael Pavone
mem_pointers for the sega/SSF2 mapper. Invalidate RAM code ranges on RAM deserialization
2017-08-29Fix savestate path calculation in genesis load_stateMichael Pavone
2017-08-28Save and restore Z80 bank register in native save statesMichael Pavone
2017-08-27Save/restore mapper state in native save statesMichael Pavone
2017-08-24Allow actually saving a save state in more Z80 states. Save busreq/reset ↵Michael Pavone
state in bus arbiter section for "native" save states
2017-08-16Added save states to SMS emulationMichael Pavone
2017-08-09New savestates are working. New config file option for selecting format ↵Michael Pavone
states will be saved in. Mostly complete, needs a little more work before release
2017-08-06WIP - New savestate formatMichael Pavone
2017-06-26Fix DMA from byte-wide SRAMMichael Pavone
2017-06-24Support a couple of bootleg X-in-1 cartsMichael Pavone
2017-06-23Move I2C EEPROM and NOR Flash functions out of romdb.c into new filesMichael Pavone
2017-06-15Properly release and reacquire framebuffer pointer when switching contexts. ↵Michael Pavone
Hopefully fixes the LOCKRECT issue some people are seeing with the SDL 2 fallback renderer
2017-06-07Initial work to support parallel NOR flash and the Magistr 16Michael Pavone
2017-05-28Implemented SMS pause buttonMichael Pavone
2017-05-23Go back to resetting the refresh counter after a DMA. Probably not quite ↵Michael Pavone
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)
2017-05-23Fixed regression from VDP sync changes. Direct color DMA demos are now ↵Michael Pavone
achieving stable sync again
2017-05-23Attempt at improving refresh emulationMichael Pavone
2017-05-23Remove HINT_FUDGE and make a small adjustment to how VDP syncs with rest of ↵Michael Pavone
system instead. Worse results on CRAM dot issue, but much less of a hack
2017-05-19Added some code to try and prevent Z80 accesses and refresh cycles from ↵Michael Pavone
screwing up interrupt latency more than on hardware
2017-05-08Implemented slow rise time of IO pins set as inputs, but not driven by ↵Michael Pavone
device. Fixes input in Decap Attack and possibly other games with buggy controller code
2017-04-26Small tweak to how SAT cache updates are done. Mostly fixes the rotating ↵Michael Pavone
cube scene in Overdrive 2
2017-04-21Fix a deficiency in the way types were handled in my ternary tree. Fixes in ↵Michael Pavone
which some paths that were constructed from a template with variables would sometimes get an extra garbage character thrown in
2017-04-16Initial work on handling the 128KB VRAM mode bit and some basic prep work ↵Michael Pavone
for VDP test register support
2017-04-15Fix copy pasta error in handling of Z80 VDP port reads. HV counter reads are ↵Michael Pavone
not illegal writes =P. Fixes immediate exit in Overdrive II, though other problems remain
2017-03-30YM2612 should also be reset on system soft resetMichael Pavone
2017-03-30Reset YM2612 whenver the Z80 is reset. Fixes issue with stuck notes in ↵Michael Pavone
