CTRDG_CpuCopy*

C Specification

#include <nitro/ctrdg.h>
BOOL CTRDG_CpuCopy8( const void* src, void* dest, u32 size );
BOOL CTRDG_CpuCopy16( const void* src, void* dest, u32 size );
BOOL CTRDG_CpuCopy32( const void* src, void* dest, u32 size );

  

Arguments

src The transfer source address.
dest The transfer destination address.
size The transfer size (in bytes).

Return Values

Returns a value of TRUE if the transfer succeeds. Returns a value of FALSE when there is no Game Pak or if the transfer fails.

Description

These functions transfer data that is on the Game Pak using the CPU.

CTRDG_CpuCopy8   transfers data   8 bits at a time.
CTRDG_CpuCopy16 transfers data 16 bits at a time.
CTRDG_CpuCopy32 transfers data 32 bits at a time.

These functions do not set the access cycle. The access cycle must be set in advance.

CTRDG_CpuCopy8() writes in units of 8 bits. It cannot access VRAM directly.

Internally, CTRDG_CpuCopy16() uses MI_CpuCopy16() and CTRDG_CpuCopy32() uses MI_CpuCopy32().
