don't use R4III or R4 smilar....just use the original R4 that is the first cart for NDSL. I'm using wood R4 1.12 for my cousin R4.....very neat and accept all new games.
sorry i dun know cos i only go simlim buy computer stuffs only but i recommend u fun centre or funzsquare which is not in simlim.
call them to confirm before going down first.
