@azushark seeing you talking about remixes has me thinking, you might appreciate some of the 'demakes' that we made a few years back, if you're interested. We took some good video game music and arranged it with famitracker into something you could play on a famicom (I like that square-wave sound!). Some of them also use the VRC7, of which the audio portion is a stripped-down OPLL (which itself is a stripped-down OPL2)
