goyuken 0fb5be2420 NES: FDS: audit and clean up audio module. in the process, fix a few bugs; opening to Metroid sounds correct now 2012-12-15 16:51:04 +00:00
goyuken 3cfc57f8a1 7800: ignore 128 byte header, if present 2012-12-15 16:06:35 +00:00
goyuken 0e0359613d mmc5 audio: oops 2012-12-15 15:17:23 +00:00
goyuken 2983c23920 atari7800: control hooked up, more or less 2012-12-15 02:36:38 +00:00
goyuken 1895103a9c atari 7800: did controller stuff until i got annoyed 2012-12-15 00:58:55 +00:00
goyuken a9bf3cf58a nes: apu: implement "better" mixing scheme (as recommended by nesdev) in the hope of passing some apu_mixer tests. no change in any of the tests, so change backed out (committed as comments only). from what i understand, it's just as likely that the tests are failing to small channel timing problems as mixer problems. 2012-12-14 22:29:27 +00:00
goyuken bab873fa13 mmc5: fix bug in pcm audio that i didn't even know about because nothing ever uses it at all. sunsoft 5b: implement audio. affects Gimmick(J). note that the audio emulation is rather incomplete. 2012-12-14 21:06:58 +00:00
goyuken c90d2dcd56 nes: MMC5: change prg ram behavior to mask out of range banks. seems to fix Shin 4 Nin Uchi Mahjong: Yakuman Tengoku (新４人打ちマージャン 役満天国). i have no idea what's actually going on 2012-12-14 19:46:01 +00:00
goyuken a4f3c2a7de NES: ExROM: Support "HVC-EKROM". Fixes good dumps of: 
Just Breed (ジャストブリード)
Royal Blood (ロイヤルブラッド)
Shin 4 Nin Uchi Mahjong: Yakuman Tengoku (新４人打ちマージャン 役満天国)
 2012-12-14 19:35:43 +00:00
goyuken 6ca1886933 MMC5: audio. PCM is untested because i don't know of anything at all that actually uses it. 2012-12-14 18:41:16 +00:00
goyuken 37e2dfbc9a nes: namco 163: make audio somewhat louder, based on listening to a few cart recordings. still softer than fceux 2012-12-14 18:38:13 +00:00
goyuken 5986d779e7 SMS: increase size of buffer for public byte[] SaveStateBinary() by 1 byte. also throw an exception if the savestate is smaller than expected. 2012-12-14 16:59:23 +00:00
goyuken 4e0796814d VRC6 audio: restructure to send deltas directly to the NES apu, simplifying some things. This would be pointless masturbation by itself, but this method will also lead to easier emulation of MMC5 audio. 2012-12-14 15:17:14 +00:00
goyuken 3bcb00f9b9 vrc6 audio: fix off-by-one in frequency counts 2012-12-14 14:38:39 +00:00
adelikat d34368e98d Atari 7800 - hook up input on client side, implement joystick button 2 in controller definition 2012-12-14 02:17:47 +00:00
goyuken e31f4380e2 nes: vrc7: change patchset to one recommended by nesdev. i dunno... sounds better? maybe? 2012-12-14 01:36:01 +00:00
goyuken 77b1d2e207 delete old 7800 stuff 2012-12-12 19:40:42 +00:00

goyuken 0636bda89d 7800: savestates 2012-12-12 15:36:17 +00:00
goyuken 7bb1baf2ab the hsc in a 7800 is supposed to be a saverammy thing, so hook it up as such. dunno if it actually works 2012-12-12 03:47:05 +00:00
goyuken f32fc83d96 7800: integrate the existing emu7800 gamedb as a core-private gamedb (not unlike bootgod), and use that to drive decision making. emu7800 should now be able to correctly load 7800PAL and 2600 games. 2012-12-12 03:40:18 +00:00
adelikat fb7873a6a7 Atari 7800 - better use of the Cart object, not a very useful commit though since it is still hardcoding the mapper 2012-12-12 01:59:10 +00:00
goyuken a43ecbf6aa 7800: speed up framebuffer blits, and add audio output 2012-12-12 01:32:58 +00:00
goyuken c22ad34844 7800: you can see stuff that doesn't look retarded now 2012-12-12 00:30:36 +00:00
goyuken da0a8822c9 7800: you can see stuff now 2012-12-12 00:23:01 +00:00
goyuken 821e2e26e3 atari7800: progress 2012-12-11 23:01:01 +00:00
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 a1065942ed old VRC6 sound moved to attic/ 2012-12-10 20:26:59 +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
goyuken 1b83110a37 C64: connect audio to speexresampler. consider this commit a demonstration on "how it could be done"... 2012-12-08 16:05:00 +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

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 8e55810161 commodore64: more video function implemented in the new system, 12 pixel delay also applied to border 2012-11-28 06:21:52 +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

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
