Sega Genesis games that don't use PCM?
Is there an easy way to tell which YM2612 games don't use PCM? Is it as simple as looking at vgm2txt for the "YM2612 DAC DISABLE" line near the top? Thanks!

A "DAC disable" command is not a clear indication. Some games switch between FM6 and DAC mid-song.
However, checking for YM2612 PCM data blocks (bytes 67 66 00) is a good indication, because 99% of the VGMs make use of the YM2612 PCM optimization.
The data blocks are usually located at the very beginning of the VGM.
If such a data block exists, PCM samples are used. If it doesn't then no PCM is used.
