#include <nitro/ctrdg.h>u16 CTRDG_GetAgbMakerCode( void );None.
Returns the maker code for an existing AGB Game Pak if it matches the one obtained when the CTRDG_Init function was called.
Otherwise returns FALSE. Also, always returns FALSE after the Game Pak has been removed once.
Returns the AGB Game Pak's maker code.
However, if there is no AGB Game Pak or the maker code does not match the code retrieved by the CTRDG_Init function, FALSE is returned.
This function can be called when the cartridge bus is locked with the OS_LockCartridge function. However, while the bus is locked, the ARM7 does not detect removal automatically, so call the CTRDG_IsExisting function at regular intervals, such as each game frame, during which the player cannot perform a re-insert operation. (This function internally calls the CTRDG_IsExisting function.)
If the maker code obtained when the CTRDG_Init function was called matches the one obtained again in this function, that value will be returned.
Accordingly, note that Game Paks enabled after the CTRDG_Init function is called will not be recognized.
(For details, see the description of the CTRDG_Init function.)
