Expand description

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 0x00RustyNES’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.
