Detailed Description

API for features of the Memory Card Maple Function

The Memory Card Maple function is for exposing a low-level, block-based API that allows you to read from and write to random blocks within the memory card's filesystem.

Note: A standard memory card has a block size of 512 bytes; however, the block size is a configurable parameter in the "root" block, which can be queried to cover supporting homebrew memory cards with larger block sizes.

Warning: You should never use these functions directly, unless you really know what you're doing, as you can easily corrupt the filesystem by writing incorrect data. Instead, you should favor the high-level filesystem API found in vmufs.h, or just use the native C standard filesystem API within the virtual /vmu/ root directory to operate on VMU data.

Function Documentation

◆ vmu_block_read()

int vmu_block_read	(	maple_device_t *	dev,
		uint16_t	blocknum,
		uint8_t *	buffer )

Read a block from a memory card.

This function performs a low-level raw block read from a memory card.

Parameters

dev	The device to read from.
blocknum	The block number to read.
buffer	The buffer to read into (512 bytes).

Return values

MAPLE_EOK	On success.
MAPLE_ETIMEOUT	If the command timed out while blocking.
MAPLE_EFAIL	On errors other than timeout.

◆ vmu_block_write()

int vmu_block_write	(	maple_device_t *	dev,
		uint16_t	blocknum,
		const uint8_t *	buffer )

Write a block to a memory card.

This function performs a low-level raw block write to a memory card.
