Struct Rom

pub struct Rom { /* private fields */ }

Implementations

impl Rom

pub fn new(data: Vec<u8>) -> Self

pub fn load(&self, address: u32) -> u8

CPU memory address: 0x0000 - 0x1FFF: Character ROM access 0x8000 - 0xFFFF: Program ROM access

To access wide range ROM data with limited CPU memory address space Mapper maps CPU memory address to ROM’s. In general writing control registers in Mapper via .store() switches bank.

pub fn load_without_mapping(&self, address: u32) -> u8

pub fn store(&mut self, address: u32, value: u8)

In general writing with ROM address space updates control registers in Mapper.

pub fn valid(&self) -> bool

pub fn has_chr_rom(&self) -> bool

pub fn mirroring_type(&self) -> Mirrorings

pub fn irq_interrupted(&mut self) -> bool
