Watara Supervision
a failed competitor of Game Boy, straight from Taiwan. released in 1992, it had a tilting screen, $50 price tag, very fast 4 MHz 6502-like CPU, framebuffer graphics and sound capabilities similia to Game Boy.
these are 2 pulse wave channels (same as on GB), barely working PCM channel and noise channel, also not unlike Game Boy. no hardware envelopes or zombie mode, though

info
this chip uses the Watara Supervision and Generic Sample instrument editors.
sample info
sample channel is 4-bit DMA channel with 4 frequencies assigned to sample octaves (C2, C3, C4, C5; C, C#, D, D# in furnace respectively). max sample size is 4 kilobytes (8192 samples).
chip config
the following options are available in the Chip Manager window:
- Swap noise duty cycles: enabled by default. when enabled, short noise is on odd-indexed duty cycles, like on Game Boy, rather than even.
- Stereo pulse waves: disabled by default. when enabled, it forces pulse channel 1 to the right output channel and second pulse to the left output channel.
