Sound Expander for Commodore 64
OPL FM Sound expander cartridge for Commodore 64, it's placeholder until OPL is implemented.

MSX's sound standard, appeared after MSX-AUDIO. it's basically OPLL FM sound expansion for MSX.

Sound Blaster w/Game Blaster Compatible
Earliest Sound Blaster models has featured with Game Blaster compatiblity, It's has 2 SAA1099s like CMS/Game Blaster. It's removed at later models, but some hardware has just empty socket; you can restore this feature when you mount SAA1099 at empty socket.
Sharp X1:
Predecessor of X68000. it has built in AY PSG like competitors of the same period, but it has YM2151 FM sound addon in later models. FM sound is embedded in turbo Z, and that is succeeded by X68000.
X68000 hasn't AY, instead OKI MSM6258.
YM2151 in OutRun Board and X Board is 4MHz
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
this commit mostly rewrites the sample system.
as of now samples can be ADPCM, 8-bit, BRR or 16-bit
or something...
consider this VERY EXPERIMENTAL.
if you find any issues REPORT THEM immediately.
it's nearly 4am...
as of now compound systems (Genesis and Arcade) are translated to
separate chips.
this improves audio quality and makes things easier.
it also allows you to change the volume of each chip on a Genesis.
also adds SegaPCM system with 16 channels!
