Wavetables are variable size and freely allocable anywhere in RAM, it means it can use part of or continuously pre-loaded waveform and its sequences in RAM.

+This is one of Namco's NES mappers, with up to 8 wavetable channels. It has also 256 nibbles (128 bytes) of internal RAM, and both channel registers and wavetables are stored here. Wavetables are variable in size and freely allocable anywhere in RAM, it means it can use part of or continuously pre-loaded waveform and its sequences in RAM. At least 128 nibbles (64 bytes) can be dedicated to waves, with more available if not all channels are used - waveform RAM area becomes smaller as more channels are activated, since channel registers consume 8 bytes for each channel. You must avoid conflict with channel register area and waveform to avoid broken channel playback.
 
-It outputs only a single channel at clock; so its sound quality gets more crunchy as more channels are activated.
+Namco 163 uses time-division multiplexing for its output. this means that only one channel is output per sample (like OPLL and OPN2). therefore, its sound quality gets worse as more channels are activated.
 
 Furnace supports loading waveforms into RAM and waveform playback simultaneously, and channel limit is dynamically changeable with effect commands.
 You must load waveform to RAM first for playback, as its load behavior auto-updates when every waveform changes.
