# CTRDG_VerifyAgbSram

## C Specification

      #include <nitro/ctrdg.h>

      u32 CTRDG_VerifyAgbSram(u32 tgt, const void* src, u32 size);

      Corresponding AGB function: u32 VerifySram(u8 *tgt,u8 *src,u32 size)

## Arguments

tgt | Represents a pointer to the SRAM address to be verified (data to be written, address in the AGB memory map)
src | Represents a pointer to the verification source work area address (original data)
size | Represents the size of data verified in bytes

## Return Values

Returns 0 if verification succeeds. Returns the error address on the device side if verification fails.

## Description

This function verifies data of the size given by "size" from the address in the work area given by "src" against the data at the address given by "tgt" in SRAM.
This function returns 0 if verification ends correctly; otherwise, it returns the address where the verification error occurs.

The access cycle setting is created in the function and does not need to be set beforehand.

Note: The cartridge bus is locked for a set period by this function.
In addition, the AGB backup device cannot be accessed normally by the IS-NITRO-DEBUGGER.
However, be sure to check operations using an actual DS handheld unit since normal access is possible with actual DS units. (This will be fixed in a future version of IS-NITRO-DEBUGGER.)
