i tried to make a Famicom-ish song that isnt just limited to the 2A03 channels but also the S5B soundchip's channels (3 extra square waves) with the closest resembleance instruments for this thing, not 100 percent accurate but atleast its pretty close
this all began because i remember someone mistaking PtCollab for FamiStudio.., rather silly
this was very fun overall though

cool! would love to hear more!
