goyuken 0aa5e2a512 NES: try implementing SEEPROM for BANDAI-FGC boards. Seems to work reading, but I can't get far enough into any of the games for writing. Like the rest of the mapper, only works with crc id because I don't know how to positively identify any of this from ines headers. Affected games:

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 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 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 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 c3a74edd7f VRC6 sound: cleanup, implement $9003 2012-12-10 16:09:49 +00:00
goyuken 5590898c46 VRC6: fish crash bug on loading non-VRC6 games in some cases (caused by recent commit) 2012-12-10 02:41:54 +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 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
