# 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 similar 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.
|
|
|
|
## effects
|
|
|
|
- `12xx`: **set duty cycle/noise mode.**
|
|
- range is `0` to `3` for pulse and `0` to `1` for noise.
|
|
|
|
## info
|
|
|
|
this chip uses the [Watara Supervision](../4-instrument/watarasv.md) and [Generic Sample](../4-instrument/sample.md) instrument editors.
|
|
|
|
### sample info
|
|
|
|
the sample channel is a 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), samples are padded to multiples of 32 samples, and loop points are ignored.
|
|
|
|
## 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.
