More pcm chips support

[Ultraprogramer]

This is probably kinda that a duplicate of #14 but instead i am requesting other chips.

Update: Since most of the chips have been added, I updated the suggestion only showing the chips that were requested that haven't been implemented yet:

• Namco C352 (32 pcm channels)
• OPL4 (18 fm channels + 24 pcm channels) [OPL4 and multipcm are currently being done on a separated pull request]
• RF5C400 (32 pcm channels)
• Nec upd7759 (1 channel adpcm)

I would like to request Konami K053260 - one of thousands of YM2151 PCM companions, used in some later Konami arcades. More info: https://vgmrips.net/wiki/Konami_K053260

[freq-mod]

It got implemented already

[Ultraprogramer]

I added it to the list.

I would like to request the Nintendo (Sony?) S-SMP chip - the sound chip for the SNES.

[Ultraprogramer]

The sony s-smp chip is already planned for the 0.6 release.

[The789Guy]

Oh. okay.

According to Wikipedia (so take this with a grain of salt), Soundblaster uses ADPCM compression and, on 1.0 and 1.5, plays back 8-bit mono samples at up to 23khz. 2.0 brings it up to 44.1 and Pro allows for stereo samples, though only at 22.05khz when in stereo.

irem ga20 is being worked on. (#787)

Ok.

[tildearrow]

that will close this issue

No, it won't

[tildearrow]

What? It's not over yet!

[freq-mod]

K053260 is partially implemented (lacks ADPCM)

[tildearrow]

Now it is fully implemented.

[tildearrow]

Konami K054539 (8 pcm/dpcm channels)

This one will not be implemented until we have proper, confirmed emulation...

I have no idea how helpful this would be in the slightest, but I recently learned about this: https://github.com/sebknzl/krawall
It is just an s3m/xm player at the end of the day, but it could be useful for getting GBA into Furnace. I am also not sure if its license (LGPL) is compatible with Furnace. I wish I knew more, but bringing awareness is something I can do at least.

[tildearrow]

Furnace isn't FastTracker 2.

[IceDragonDee]

Also, I've been told that the license isn't compatible anyway.
But even though it isn't FT2, surely (if the licence was compatible), there could be something to glean, mainly with how channels are split and how the sample rate is calculated.
