saxxonpike	31fba1ec2b	commodore64: change from uint to int, seems to speed things up a little with no side effects	2012-12-11 06:27:00 +00:00
saxxonpike	5a8ce4000b	commodore64: clean up unneeded files since the Sid is hooked up to the Speex resampler now	2012-12-10 22:51:02 +00:00
goyuken	cc4b683006	7800: change HSC ram size from 4096 bytes to 2048 bytes (i think this is correct), and send logging messages to the log window. doesn't run still.	2012-12-10 21:29:50 +00:00
goyuken	638c358b5d	fix compile error from last commit	2012-12-10 20:36:51 +00:00

goyuken	43396d4b39	garbodev disconnected and moved to attic/	2012-12-10 20:24:21 +00:00
goyuken	4784ab2006	garbodev: fix up all problems in the IEmulator sound binding. what you hear now, is what garbodev ACTUALLY SOUNDS LIKE. wow.	2012-12-10 20:11:10 +00:00
goyuken	4834f40f6c	play around with garbodev core. probably worse than meteor, in general. managed. small compile-time change in MainForm.cs is needed to switch between the two. garbodev source files don't have any license on them at all, so 99.99% chance that this will be axed. why did i do it?	2012-12-10 19:32:18 +00:00
goyuken	c3a74edd7f	VRC6 sound: cleanup, implement $9003	2012-12-10 16:09:49 +00:00

goyuken	49f16bcb20	nes: vrc6: new audio implementation. sounds awesome	2012-12-10 01:13:12 +00:00
zeromus	a4b442abda	unify coreinputcomm and coreoutputcomm. there is a slight chance your console will be messed up until i fix a teeny tiny something, since i didnt test them all, since with more recent cores i dunno what roms are working anyway. let me know if i broke anything.	2012-12-10 00:43:43 +00:00
goyuken	6ef2913ed8	WHAT ... no, it doesn't fix anything	2012-12-09 23:05:31 +00:00
goyuken	4a673e614b	nes: apu: remove unbiasing from apu core. blip_buf already handles a dc bias removal internally, and keeping all of the values to the mixer in their original forms is simpler code and probably reflects the underlying hardware more accurately. should sound about the same as before.	2012-12-09 20:39:29 +00:00
goyuken	b9f37d7ed8	dcfilter: more correct algorithm. doesn't sound any different. speed unchanged.	2012-12-09 20:02:43 +00:00
goyuken	34a6248606	nes: FDS: use blargg's blip_buf. there are still problems with the audio channel though...	2012-12-09 17:07:34 +00:00
goyuken	cb4288ada4	rearrange the api of DCFilter a bit to make it less dumb. nothing of real importance	2012-12-09 15:58:55 +00:00
goyuken	210d415e3d	Add Blargg's "blip_buf" as an unmanaged dll. license is LGPL; if I like the way it works, I'll rewrite it with MIT code. Implement it as the new resampling output track for NES. Small (~3%)? speedup. Should sound better, especially when the emulator can't quite keep speed.	2012-12-09 03:13:47 +00:00
goyuken	6f6ee16cf3	C64: fix unmanaged memory leak in most recent commit	2012-12-08 16:07:06 +00:00

saxxonpike	0907de61cc	commodore64: fixed sprite DMA delay timing, should make very time-sensitive intros run better and some games as well	2012-12-02 22:15:08 +00:00
goyuken	451f786660	snes: fix crash with rewind enabled in tales of phantasia. the problem seems to be that during runtosave(), the smp hits a wait opcode (0xff), which it can't get out of. with this fix, the emulator no longer crashes, but the emulated game does crash. more research is needed.	2012-12-02 18:32:33 +00:00

saxxonpike	d734d0f44f	commodore64: 6510 hard reset now loads startup vector AFTER banks are initialized, more carts start up now	2012-12-01 10:42:46 +00:00
saxxonpike	d951094e6d	commodore64: Add 6526 2-cycle timer delay, seems to pass more tests now. CPU Dataport inputs on lower 3 bits are always high now, may fix some paging issues. Fix joystick input so that only port A is affected on pure outputs.	2012-12-01 08:40:08 +00:00
zeromus	db37a6f64f	snes-reset the libsnes core (with whatever serious re-initialization logic we've currently written in libsnes) every time loadstate occurs; and add memsetting to that re-initialization logic, under the theory that if there is a savestate nondeterminism due to fundamental serialization bugs, at least loadstates will be deterministically buggy, decreasing the odds that anyone will ever notice them. of course, i would rather increase the odds that we'll notice them to 100%, so we can fix them, instead of just masking them. but i don't make the rules, i just stfu the nags	2012-12-01 06:21:53 +00:00
saxxonpike	08c83a16fd	commodore64: joystick input now works 100% accurately (tested with ciaports.prg from the VICE test suite)	2012-12-01 00:02:24 +00:00
saxxonpike	3049098afb	commodore64: connect IRQ and NMI lines to cartridge port (no games seem to use them but it is in the schematic)	2012-11-30 23:20:35 +00:00
saxxonpike	ae8566a0df	commodore64: made some input changes (more fixes to come later), removed some duplication in pin information between PLA, CPU and cartridge port	2012-11-30 21:12:23 +00:00

saxxonpike	e4c760be83	commodore64: fixed Ultimax E000 mapping, updated mapper 0000, added EzFlash mapper 0020 (no official games use this but a lot of disk-to-cart and homebrew do)	2012-11-29 17:58:35 +00:00
saxxonpike	1eca7805cf	commodore64: add cartridge mapper 0012 (Zaxxon, Super Zaxxon), fix mapper 0000 to support 4k roms	2012-11-29 16:33:04 +00:00
saxxonpike	d05bd47ed0	commodore64: add cartridge mapper 0005 (Ocean), should cover a few high profile games	2012-11-29 06:29:42 +00:00

goyuken	32a1ac645e	fix controller bug? more information about electrical configuration of $4016/$4017 is needed. this is not a good commit.	2012-11-28 21:34:29 +00:00
goyuken	2803190666	nes: mmc3: add 256K prg option for ACCLAIM-MC-ACC. fixes "Simpsons, The: Bart vs. The World" and "Simpsons, The: Bartman Meets Radioactive Man"	2012-11-28 21:16:35 +00:00
saxxonpike	27217f119d	commodore64: adjusted BA timing for PAL (it was taking one cycle too many), makes a lot of timing-sensitive games and demos run better	2012-11-28 21:09:45 +00:00
saxxonpike	798c355c7e	commodore64: add 4 pixel background data delay, a quick hack until I can understand what's really happening	2012-11-28 19:35:48 +00:00
goyuken	b7c66cf3c2	Util.Serializer: Consume no data past the end of the last proper section. As a result, when using Util.Serializer in text mode, you MUST enclose your entire savestate in a single section (named to your liking). Fixes input log save\load issues. All old A2600 savestates broken.	2012-11-28 18:27:14 +00:00
saxxonpike	b55d6526d1	commodore64: PRG loading uses a more robust method	2012-11-28 17:49:42 +00:00
saxxonpike	e490d1be04	commodore64: input added back, this method is closer to the circuitry itself	2012-11-28 17:26:40 +00:00

saxxonpike	49a847d8bc	commodore64: VIC timing fix, implemented new cartridge I/O which handles writes into ROM addresses (apparently some carts use this)	2012-11-28 03:30:59 +00:00

saxxonpike	ccc332f8e2	commodore64: unconnected pin values in the 6510 I/O port $01 register fade over time (Aurora90%), need to verify the TTL on that sometime	2012-11-27 20:23:27 +00:00
goyuken	965c6d8700	gba: add the beginnings of a GPU view. much work is needed, but i like the idea of a single panel with movable widgets (and config-saveable layout, of course), as there is too much information in the case of a GBA to reasonably show it all on a screen. this way the user can set up a "workspace" appropriate for whatever dumping/debugging project is being done.	2012-11-27 19:21:46 +00:00
goyuken	175caf3a53	gba: add under-the-hood support for direct MMIO reading, to be used for something at some point, maybe	2012-11-27 16:44:50 +00:00

goyuken	fa388ed149	av dump: support resizing everything to a single resolution. sorry about all the crap gumming up MainForm...	2012-11-26 02:25:23 +00:00
