Whats a Nexus card?
There are two 3rd party VM cards available, the Nexus 4x and 16x memory cards. These are switched memory cards which basically function as 4 memory cards in one, or 16-in-1 in the case of the 16x card, thus giving 800 memory blocks and 3200 blocks respectively. To select a different bank, you have to press a button. One advantage of the Nexus cards is that you can get special cables and software for them which allows you to transfer save files to a PC, and vice versa, but they are also limited in the fact that they are a plain memory card, and do not offer an LCD screen or buttons for playing minigames.
