Enum PpuPalette 

pub enum PpuPalette {
    Composite2C02,
    Rgb2C03,
    Rgb2C04_0001,
    Rgb2C04_0002,
    Rgb2C04_0003,
    Rgb2C04_0004,
    Rgb2C05,
}

Which PPU palette is active for the running console.

The default 2C02 (Self::Composite2C02) is the standard NES/Famicom composite palette (NES_PALETTE + apply_emphasis). The other variants are the hardware RGB palettes baked into the Vs. System / PlayChoice-10 arcade PPUs (the 2C03 / 2C04-xxxx / 2C05), which output digital RGB rather than composite video. Selected from the NES 2.0 header byte 13 Vs. PPU type when the console type is Vs. System.

Variants

Composite2C02

Standard 2C02 NES/Famicom composite palette (default).

Rgb2C03

2C03 RGB PPU (PlayChoice-10, Vs. Duck Hunt / Tennis, Sharp C1). Shared with the 2C05.

Rgb2C04_0001

RP2C04-0001 RGB PPU (Vs. System).

Rgb2C04_0002

RP2C04-0002 RGB PPU (Vs. System).

Rgb2C04_0003

RP2C04-0003 RGB PPU (Vs. System).

Rgb2C04_0004

RP2C04-0004 RGB PPU (Vs. System).

Rgb2C05

2C05 RGB PPU — uses the 2C03 master palette (the 2C05’s quirks are the $2000/$2001 swap and the $2002 identifier, not the colors).

Implementations

impl PpuPalette

pub const fn is_composite(self) -> bool

True for the composite 2C02 (the default NES/Famicom path).

Trait Implementations

impl Clone for PpuPalette

fn clone(&self) -> PpuPalette

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for PpuPalette

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for PpuPalette

fn default() -> PpuPalette

Returns the “default value” for a type.

impl Hash for PpuPalette

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for PpuPalette

fn eq(&self, other: &PpuPalette) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
