# Namco 163
This is Namco's one of NES mapper, with up to 8 wavetable channels. It has also 128 byte of internal RAM, both channel register and wavetables are stored here. Wavetables are variable size and freely allocable anywhere in RAM, it means it can be uses part of or merged 2 or more pre-loaded waveforms in RAM. But waveform RAM area becomes smaller as much as activating more channels; Channel register consumes 8 byte for each channels. You must avoid conflict with channel register area and waveform for avoid channel playback broken.
This is Namco's one of NES mapper, with up to 8 wavetable channels. It has also 128 byte of internal RAM, both channel register and wavetables are stored here. Wavetables are variable size and freely allocable anywhere in RAM, it means it can be uses part of or continuously pre-loaded waveform and/or its sequences in RAM. But waveform RAM area becomes smaller as much as activating more channels; Channel register consumes 8 byte for each channels. You must avoid conflict with channel register area and waveform for avoid channel playback broken.
It has can be outputs only single channel at clock; so it's sound quality is more crunchy as much as activating more channels.
