I think it will be a good thing for extra sound used in games.

I'm not seeing any use in this and i'm seeing even less of a point in anyone providing support for something that was apparently only noticed just a week ago, which won't be compatible with -any- player, and likely not even in any emulator.

that'd be a good idea. At least until we all know what it is, how it works, etc.

Not like the sound chip I'm the most interested in seeing support for. We don't even know what it does yet.

Surely support for something like the Namcot 106 would be far more useful.

I think right now jsr is focusing on VRC6 for the first version to include an extra chip. MMC5 or VRC7 should be nice in the future though.

there was a version posted in the channel with very very early VRC6+7. you can't do anything with it beyond mess around a bit though.

Hey dude! It's written on the datasheet. It's a 4-bit ADPCM sampler with probably internal ROM (I don't know the exact model)

I don't even go there, so I don't even know it exists and the information isn't very useful to me because I have no access.

So, what, it's like a second DPCM channel or something?

ADPCM is better than DPCM. I think 4-bit ADPCM at 8 kHz will usually sound better than 1-bit DPCM at 32 kHz (at least, it shouldn't sound worse), and it will take up the same amount of memory. And then of course you could choose a sampling rate higher than 8 kHz, getting better sound at the expense of more memory.

It also allows more flexibility... you cannot approximate a square wave at all using DPCM, but you might be able to get something using ADPCM.

A great idea, but no nsf player seem to support it nor any emulators.
