Pretty much. That or a gameboy.
It's interesting to see how these chips use their narrow bus widths (16bit 12 samples in / 24 out in this case) to produce so many variations. Haven't looked deeper into the platform, but it would make sense to use more than one of them at a time in an asynchronous manner. Cheap, but effective. It uses even older DDR2 memory, which has even less latency and good, but is very limited to maximum memory saturation for an overall variety of samples at a given time. It's not going to go sentient on us any time soon
