Content
This is an emulation of the Nintendo/Sony sound module used in the Super NES / Super Famicom (consisting of an SPC700 processor and a custom audio DSP) that runs in one P2 cog.
Features:
- 8 channels of BRR sample playback
- 32kHz sample rate, accurate to real S-DSP
- SPC700 CPU emulation with instruction timings
Misfeatures:
- Requires ~200 MHz P2 clock or higher
(If clock isn't way too low, it fails gracefully by skipping SPC700 cycles) - Some tunes exhibit minor clicking..
- Inaccurate Timer 2 emulation
