blastem.git - Oxore's fork of "blastem" emulator for ROM hacking (C)

Age	Commit message (Collapse)	Author
2017-06-15	Properly 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
2017-06-07	Initial work to support parallel NOR flash and the Magistr 16	Michael Pavone

2017-05-28	Implemented SMS pause button	Michael Pavone

2017-05-23	Go 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)
2017-05-23	Fixed regression from VDP sync changes. Direct color DMA demos are now ↵	Michael Pavone
	achieving stable sync again
2017-05-23	Attempt at improving refresh emulation	Michael Pavone

2017-05-23	Remove 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
2017-05-19	Added some code to try and prevent Z80 accesses and refresh cycles from ↵	Michael Pavone
	screwing up interrupt latency more than on hardware
2017-05-08	Implemented 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
2017-04-26	Small tweak to how SAT cache updates are done. Mostly fixes the rotating ↵	Michael Pavone
	cube scene in Overdrive 2
2017-04-21	Fix 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
2017-04-16	Initial work on handling the 128KB VRAM mode bit and some basic prep work ↵	Michael Pavone
	for VDP test register support
2017-04-15	Fix 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
2017-03-30	YM2612 should also be reset on system soft reset	Michael Pavone

2017-03-30	Reset YM2612 whenver the Z80 is reset. Fixes issue with stuck notes in ↵	Michael Pavone
	Fantastic Dizzy and Kid Chameleon
2017-03-28	Fix exit trace mode edge case. Call do_sync if trace mode bit is changed in ↵	Michael Pavone
	eori sr
2017-03-28	Implemented M68K trace mode. Some edge cases/SR update paths still need work	Michael Pavone

2017-03-19	Adjust Z80 interrupt pulse duration to match hardware measurements	Michael Pavone

2017-03-19	Minor fix to hacky refresh emulation code to more closely match my intent	Michael Pavone

2017-03-18	Basic refresh emulation that doesn't break direct color DMA demos. Fixes ↵	Michael Pavone
	sound after entering pause menu in Pacman 2: The New Adventures
2017-03-18	Remove hacky post-DMA delay add proper pre-DMA delay based on logic analyzer ↵	Michael Pavone
	capture. 512 color screen is a bit messed up but mostly works. Needs investigation
2017-02-14	Add mising include in genesis.c so the Windows build works again	Michael Pavone

2017-02-01	Basic implementation of serial IO registers, but without actual serial IO ↵	Michael Pavone
	support. Needed to run a certain software check cartridge that is floating around.
2017-01-27	Implement soft reset in Genesis mode	Michael Pavone

2017-01-26	Added config file option to specify that RAM should be randomly initialized. ↵	Michael Pavone
	Moved default_region inside a new "system" parent node in config
2017-01-22	Fix missing include that prevented building Windows version	Michael Pavone

2017-01-18	Overscan is now configurable	Michael Pavone

2017-01-15	Don't adjust cycles every frame. Only when we start getting close to ↵	Michael Pavone
	UINT_MAX. Don't adjust all the way down to zero when we do adjust. Shouldn't fix anything, but may make debugging current issues easier.
2017-01-10	Fix crash regression for games with some kind of mapper functionality	Michael Pavone

2016-12-28	Remove memory map assumptions from Z80 core and move a little bit of logic ↵	Michael Pavone
	to the generic backend.c so it can be shared between CPU cores
2016-12-22	Initial support for Genesis/Megadrive PBC mode. VDP still needs Mode 4 to be ↵	Michael Pavone
	useful.
2016-12-22	More cleanup in preparation for SMS/Mark III support	Michael Pavone

2016-12-19	Restore 68K address logging functionality	Michael Pavone

2016-12-19	Mostly working changes to allow support for multiple emulated system types ↵	Michael Pavone
	in main blastem program
2016-12-14	Fix Z80 interrupt pulse duration. Fixes inconsistent music playback speed in ↵	Michael Pavone
	Sonic 2 introduced in 0.4.1
2016-12-11	Fix Z80 RAM mapping after refactor	Michael Pavone

2016-12-09	Fix the previous WIP commit. Quick tests suggests things are no more broken ↵	Michael Pavone
	than before now.
2016-12-09	WIP split of ROM loading/argument parsing from Genesis emulation code. ↵	Michael Pavone
	Compiles and doesn't crash, but nothing works. Still a few too many globals as well.
