Struct RamCard 

pub struct RamCard { /* private fields */ }

A 128 KiB card held entirely in memory.

The struct owns the full image inline (128 KiB), so place it in a static or box it on the heap rather than passing it around by value on the small PS1 stack.

Implementations

impl RamCard

pub const fn new() -> Self

A blank (all-zero, unformatted) card. Call crate::Card::format to lay down a valid directory.

pub fn from_image(image: &[u8]) -> Result<Self>

Build from an existing 128 KiB image (e.g. a .mcd file loaded on a host).

pub fn image(&self) -> &[u8; 131072]

Borrow the raw 128 KiB image (for persisting to a host file).
