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
arm9romif true the arm9 is the owner of slot 2, otherwise the arm7
arm9cardif true the arm9 is the owner of slot 1, otherwise the arm7
static void sysSetCardOwner ( bool  arm9)
inline

Sets the owner of the DS card bus. Both CPUs cannot have access to the DS card bus (slot 1).

Parameters
arm9if 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
arm9if true the arm9 is the owner, otherwise the arm7
