Bubble System WSG

A Konami-made 2-channel wavetable sound generator logic used on the Bubble System arcade board, configured with K005289, a 4-bit PROM and DAC. However, the K005289 is just part of the logic used for pitch and wavetable ROM address. Waveform select and volume control are tied with a single AY-3-8910 I/O for both channels. Another AY-3-8910 I/O is used for reading sound hardware status. Furnace emulates this configuration as a “chip” with 32×16 wavetables.
