The N5 Revolution for DS (simply referred to as 'N5' from this point on) is a new flashcart that is simply a direct clone of the R4 DS. Not much information has been released about this cart to far, however this review will only be short because this cart is nearly exactly the same as the R4 DS. N5 DS or DS N5 is a multi functional media adapter for NDS. It accepts MicroSD cards. N5 DS allows use of Homebrew DS applications, multimedia (via Moonshell) and commercial NDS applications via the SD interface. N5 DS is easy to use, just load the N5 DS OS onto the MicroSD together with your favorite applications, plug into N5 DS then insert the N5 DS cartridge into the DS and you're ready to go! Colourful Zone did a great job of improving the dreaded issues with the N5. This makes it slightly worth it to purchase now. But as mentioned above, I personally preferred the spring loaded microSD slot. To determine which version you have, CZ places a small CZ sticker on the box. They also place 3 more on the cartridge itself (front, back and top). This is overkill. You only need one; front or on top next to microSD slot. So if you're looking to get the N5, CZ is the place to get it as they have fixed the problems no thanks to N5.
