Hey!
If you check the comments, you will find some comments about the DAC. Still not sure where there are any DAC (PCM) sounds, I just want to say:
the DAC WAS disabled while I recorded that, as well as the PSG, which is not used AT ALL by those tunes.

The so-called "DAC"-percussion (e.g. in the ISLANDS song, there are these bongos on the left channel and the steel drum-like songs and crashes) is not PCM, just plain FM instruments.
If you disable any other than the 6th channel you will hear it sounds more like a "noise" generator found in many sound chips for game consoles and FM like sounds.

"Real" DAC percussion can be found in SONIC (2,3,Crackers,...), KID CHAMELEON and many other games. If you want to hear a heavy usage of the DAC, check COMBAT CARS! You'll hear the difference between those cute sounds here and the heavy DAC sounds.

The YM3812 (AdLib, SB) also has some percussion shipped with which sound real, but are not
waveform audio...
If you have anything to add, please let me know! Greetings.

Old, previous text:
These songs doesn't use either the DAC nor the PSG at all. It has been composed without those supportive "addons".
(The 6th channel which would be used for the digital effects is used for FM sounds instead).
