Reading from 4000640h to get the active matrix

Pretty much a question for mic, unless other NDS programmers can answer this question.

 

As much as I can do matrix calculations manually, I hear that on hardware, matrix calculations are faster, so I am hoping to use hardware instead. From documentations, it is said at area 4000640h is a 64 byte region where the active matrix can be read at. In my case, I have no means to check on hardware for the time being, so I'm going strictly emulators for testing. Problem though is that when running under an emulator, all I ever read from that section of memory are 0s, nothing else.

 

Pretty much my question(s) are if Dualis has this portion emulated? Am I correct that this area of memory is where I can grab the internal matrix from? If this is the wrong place, could I be pointed to where the correct place is?
