Functions
void	sysSetBusOwners (bool arm9rom, bool arm9card)
	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.
void	sysSetCardOwner (bool arm9)
	Sets the owner of the DS card bus. Both CPUs cannot have access to the DS card bus (slot 1).
void	sysSetCartOwner (bool arm9)
	Sets the owner of the GBA cart. Both CPUs cannot have access to the gba cart (slot 2).

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
