It did indeed fix it. What you listen for is the hi hats that play out of the noise channel. In the previous build in some tracks they sounded less like hats and just more like noise..clicks (no idea what the terminology for that is) There are a few hacks with what I'm guessing is a different sound engine that causes the same thing, but it's also heard in sound effects (monitor breaking, spindash release, etc)
Thanks for the confirmation.
What happened is this: the noise channel usually (almost always) uses a maximum frequency PSG note. In S1/S2 drivers, it is note $C6, while in S3/S&K/S3D drivers (and mine, since it is based off the S&K driver), there are two such notes, $D3 and $D4 (both of which are used). The difference is due to 13 PSG notes that the S3+ drivers have (12 at the start, one at the end). Songs converted between these drivers need to account for the difference; the previous versions of SMPS2ASM did not account for that, leading to broken noise channels in songs that were converted either to S3+ drivers from S1/S2, or from S3+ drivers to S1/S2.
