16-bit mode is implemented in the POKEY back-end, but isn't producing results that are useful or make sense. The hardware documentation of this feature is sparse to begin with, but my understanding is that it essentially enables a 16-bit frequency by sharing frequency registers between neighboring oscillators (1+2, 3+4). The panel logic to turn the feature on is in place, but currently disabled until the back-end issues are resolved.
