}

Read-only debug snapshot of mapper-internal state for the UI.

Mappers override [Mapper::debug_info] to surface their banking registers and any IRQ-counter state. Fields are pre-formatted strings so the UI doesn’t have to know the protocol of each mapper.

Fields

mapper_id: u16

Mapper id (e.g. 4 for MMC3).

name: String

Human-readable mapper name (e.g. "MMC3 (Sharp)").

mirroring: &'static str

Current mirroring layout name ("Horizontal", "Vertical", "SingleScreen", "FourScreen").

prg_banks: Vec<(String, String)>

PRG bank registers — one (label, value) entry per register the mapper exposes. Values are hex-formatted by the mapper.

chr_banks: Vec<(String, String)>

CHR bank registers — same shape as prg_banks.

irq_state: Vec<(String, String)>

IRQ counter state — (label, value) pairs, e.g. [("counter", "0x12"), ("reload", "0x80"), ("enabled", "true")].

extra: Vec<(String, String)>

Free-form extra status (envelope shape, sub-mapper flags, …).

submapper: u8

NES 2.0 submapper id (0 for iNES 1.0).

tier: &'static str

Accuracy-evidence tier name ("Core" / "Curated" / "BestEffort"), empty if the id isn’t classified.

prg_rom_size: usize

PRG-ROM size in bytes.

chr_rom_size: usize

CHR-ROM size in bytes (0 when the board uses CHR-RAM).

prg_ram_size: usize

Requested PRG-RAM size in bytes.

chr_ram_size: usize

Requested CHR-RAM size in bytes (0 when the board ships CHR-ROM).

has_battery: bool

True when PRG-RAM is battery-backed (save RAM / NVRAM present).

irq_kind: &'static str

The IRQ mechanism, when the board has one (e.g. "PPU A12 (MMC3)", "PPU scanline (MMC5)", "CPU cycle (VRC/FME-7/N163)"). Empty if the board has no IRQ source.

expansion_audio: Option<&'static str>

On-cart expansion-audio chip name, if any (e.g. "VRC6").

Trait Implementations

impl Clone for MapperDebugInfo

fn clone(&self) -> MapperDebugInfo

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for MapperDebugInfo

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

Formats the value using the given formatter.

impl Default for MapperDebugInfo

fn default() -> MapperDebugInfo

Returns the “default value” for a type.
