Any chance we'll be seeing any of the Famicom expansion chips integrated into Chipsounds?
My personal favorite is Konami's VRC6 chip which adds two pulse waves with different pulse widths (6.25% to 50% in 6.25% increments) and a saw wave. (Yeah, you can get close by selecting a SID chip, but it's still not quite right, you know?)
The Famicom Disk System also has an interesting sound chip, working similarly to the Game Boy's Wave channel with more definition (64 samples with 64 possible values, compared to the Game Boy's 32 samples with 16 possible values).
The Namco106 is similar as well, with waveforms from 4 to 32 samples long in 4 sample increments, with 16 possible values for each. It and the FDS both have 16 volume levels, though, compared to just 4 on the Game Boy's wave channel (which is another feature that would be nice to see, since Chipsounds currently only supports full volume).
There are a few other expansion chips, but some of them (MMC5 and FME7) seem to simply add more square wave channels with only minor varations, and Konami's VRC7 is FM synth.
