I know that NP21 itself has a few issues regarding PSG PCM.
It has some DC offset removal code in its PSG emulation that doesn't play nice with PMD-PPS and causes heavy distortion. However, the VGM logs are unaffected by this.
If you plan to record songs that use PSG PCM, please as in the chat first though. The PMD PPS driver does some optimization that makes it impossible to use PCM optimization tools on it.
Some time ago I made a patched PPS driver that removes the optimization and thus allows for PCM optimization as a post-processing step. (Removing the optimization also happens to reduce the distortion in NP21.)
