are you unsatisfied with how nsfplay 2.4 is playing your vrc7 containing nsf? wish it sounded more like it does in dn-famitracker? maybe you have heard of a mythical nsfplay 2.5 beta version but cannot find it on the internet. well my friend, you are in a luck. here is a hyperlink for you to click on. it was downloaded from appveyor before they decided they would no longer hold onto builds for longer than a month.
