Function Documentation

static void sysSetBusOwners	(	bool	arm9rom,
		bool	arm9card
	)

inline

Sets the owner of the DS card bus (slot 1) and gba cart bus (slot 2). Only one cpu may access the device at a time.

Parameters

arm9rom	if true the arm9 is the owner of slot 2, otherwise the arm7
arm9card	if true the arm9 is the owner of slot 1, otherwise the arm7

static void sysSetCardOwner ( bool arm9 )

inline

Parameters

arm9	if true the arm9 is the owner, otherwise the arm7

static void sysSetCartOwner ( bool arm9 )

inline

Sets the owner of the GBA cart. Both CPUs cannot have access to the gba cart (slot 2).

Parameters

arm9	if true the arm9 is the owner, otherwise the arm7
