Prepare for reducing duplicates for 4op FM related codes
Add and correct bunch of presets
- mostly based on MAME source.
- Neo Geo AES uses slightly difference clock for NTSC, PAL colorbust frequency.
- Turbosound FM + SAA: Some Turbosound FM has additional SAA1099, for additional sound channel and Plays SAM coupe tune?
- PC-98:
- Sound Orchestra: OPN with hardpanned stereo, some model has with OPL family FM addons.
V variation has Y8950 and supports ADPCM.
- Sound Blaster 16 for PC-9800: This famous PC sound card is also exists for PC-98, with optional OPN PC-9801-26(K) compatibility on some models.
- IBM PCjr: PC with SN PSG sound, but less popular than previous models, and compatible Tandy 1000.
- Tandy 1000: PCjr and previous IBM PC compatible, also has SN PSG (later embedded in their ASIC, like Sega).
- Hexion: One of konami's budget arcade hardware with SCC + MSM6295 sound system, like their amusement hardware in this era.
- DJ Boy, Atari JSA IIIs, Skimaxx: How to panning sound or plays stereo sound on MSM6295 - just use MSM6295s per each output!
- Air Buster: One of arcade hardware with OPN + MSM6295 sound system, Used this configuration is also some hardwares.
- Tecmo system: One of arcade hardware with pretty unique sound system: OPL3, YMZ280B, MSM6295; first 2 entry is mostly used in music, last entry is mostly used in sound effect.
- Sunsoft Shanghai 3: Predecessor of Sunsoft Arcade is using YM2149 rather than FM, MSM6295 is still there.
- Atari Klax: example of arcade hardware sound system with single MSM6295 only.
- Ikari warriors: This early SNK Triple-Z80 hardware uses 2 OPL1s and no ADPCM supports.
- Coreland Cyber Tank: This rare arcade machine's stereo sound is like SB Pro, but it's actually produced in 2 Y8950s.
- Data East MLC: Latest arcade hardware from Data East, with single YMZ280B for sound.
- Kaneko Jackie Chan: Predecessor of Super Kaneko Nova System hardware, also with YMZ280B.
- Super Kaneko Nova System: Latest arcade hardware from Kaneko, with single YMZ280B for sound. this announced 3D acceleration addon, but finally cancelled.
- Toaplan 1: Home of Late 80-Early 90s Good ol' stuffs, Example of arcade sound system with single OPL2
- Namco Pac-Land: and this era, Namco start to change Custom 15 WSG to their Custom 30 WSG with featured RAM based waveform, and mailbox feature.
- Namco System 1: One of latest usage of Custom 30 WSG, with OPM FM hardware and 8 bit DAC and Stereo output.
Add various clock, type options for chips
- SN7: Prepare to add 17 bit noise variation, Game gear stereo extentsion, NCR PSG variation (MAME core only for now)
- OPN, OPNA: Add placeholder for prescaler option
- OPL: Prepare for OPL3L, OPL4 downscaled output rate option
To prevent rendering samples for systems that are not in use.
Additionally, it gives the systems more flexibility to render the samples
according to their specific configuration.
as of now the SSG part of these chips is handled by a DivPlatformAY8910
within the DivPlatformYM2610.
this means less code duplication and therefore prepares for
OPN/OPNA support.
Allow 8 bit volume for YM2610 ADPCM-B
Remove sample mode macro in YM2610, it's always enabled and seperated channels.
TODO: ADPCM-B is still not implemented, FM Channel 2 is silenced in extended channel 3 configuration
