Enum PaletteInit 

pub enum PaletteInit {
    Zeroed,
    Blargg,
}

v2.1.7 P5 — selectable power-up palette-RAM contents.

The 2C02’s palette RAM is not cleared at power-on; different consoles (and thus different emulator authors’ reference dumps) come up with different garbage. This is a documented power-up option, default-off: Default (Self::Zeroed) keeps RustyNES’s established all-zero power-up palette, so default rendering is byte-identical. It writes only Ppu::palette_ram, which is already part of the save-state snapshot, so it needs no snapshot-format change.

Variants

Zeroed

Default. All 32 palette-RAM bytes power up to 0x00 — RustyNES’s established deterministic power-up state. Byte-identical.

Blargg

The canonical “Blargg” power-up palette dump (the 32-byte pattern used by blargg’s NES and mirrored by TriCNES’s BlarggPalette). A documented, deterministic known pattern for software that samples uninitialized palette RAM before writing it. Opt-in.

Trait Implementations

impl Clone for PaletteInit

fn clone(&self) -> PaletteInit

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PaletteInit

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

Formats the value using the given formatter.

impl Default for PaletteInit

fn default() -> PaletteInit

Returns the “default value” for a type.

impl Hash for PaletteInit

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

where __H: Hasher,

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 PaletteInit

fn eq(&self, other: &PaletteInit) -> 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.
