Curious, how did you get this contract?! I'd love a retro game dev gig like this. I have projects on RHDN on several different retro consoles and processors (6502 / Z80 / 65C816) and can work my way around WLA and the Mesen debugger with the best of 'em!
Also did you come up with a famicom audio expansion chip yourself? That's amazing!
I met my current employer while working within the NESDev community, and we quickly realized we lived in the same state. One thing led to another after that. This feels like one of those once-in-a-lifetime opportunities. That said, there's a surprisingly healthy market for "new retro software", or whatever we're calling new games made for 40+ year old consoles.
The expansion audio thing does indeed work on Famicom natively! For NES we plan to ship a small adapter to plug into the otherwise unused EXP port on the bottom of the frontloading console. A single resistor can bridge one of the cartridge pins to Audio Out, unlocking expansion audio for folks in the US. Works great!
