[PC engine Arch] Direct D/A Sample Playback and other tricks

[khaliewicz]

In addition to single cycle waveforms PC Engine also supports direct playback of 5-bit PCM samples. A good example would be batman with sampled bass, percussion and orchestra hits.

I think it might also be worth emphasizing the full stereo panning per channel (4-bit volume for left and right output each). This is a nice advantage vs most of it's competition at the time.

Maybe not worth mentioning but in wave mode the wave buffer can be written to during playback to produce more complex sounds.

Surprisingly not many games that did this but it might've been because you would get an small, but audible click when the sample was changed.
