Sega Genesis games that don't use PCM?

Post by superdeadite »

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.
