This chip can play 128-sample 8-bit waveforms from RAM, or 8-bit PCM samples from up to 1MB of external ROM. While this chip is capable of stereo output, no games support stereo output.
The chip is always paired with an 8kb RAM which contains the chip registers, volume envelopes and wavetables. This RAM is often shared with an external sound CPU, if present. Caution needs to be taken when stripping sound CPU writes to RAM from VGM logs.
Limitations of this chip includes a 4-bit volume register (including envelopes), 8-bit PCM sample frequency register, and 8-bit PCM sample start/loop/end registers (samples need to be aligned to every 4096 bytes).
