pub fn composite_voltage(index: usize, emphasis: usize, phase: usize) -> f32Expand description
Compute the raw composite voltage (relative to sync) for one subcarrier
phase (0..12) of NES palette index (0..=63) under emphasis (0..=7,
bit0 = red, bit1 = green, bit2 = blue).
This is the un-normalized chip output: the chosen LEVELS entry, times the
emphasis attenuation when any set emphasis bit’s hue region overlaps phase.
