Any future plans to support the Famicom to take advantage of the extra VRC chips and other sound channels not available on the NES?
No plans at this time, I'd have to acquire some hardware first.
Curious about this as well since the N8 Pro offers support for popular sound expansions out-of-the-box
The extra sound channels will most likely never be supported as it would require a major rewrite of the SynthNes ROM. I know, I'm disappointed too haha.
