For new readers, here's a quick run down of just what the R4 DS is. You may also wish to read my other article about the R4 DS Slot 1 Device. In my previous article I went into the details of exactly what the R4 DS is, what it can do, and how it works. I won't re-write all of those deatils and features here once again for the sake of saving readers who've read my previous article.You'll have to choose from a variety of card sizes depending on what kind of storage capacity you'll be needing. There are smaller ones for those who are only interested in storing a few games, or there are larger ones for people who want to store all or most of their games. If you aren't quite sure how many games you'll want to store, then you should get a 16Gbit card. This way you'll have plenty of room for your current games, as well as space to store games later on.The R4 DS Slot 1 Solution PackageIt's almost a dead giveaway here, except for the fact that the R4 DS comes in it's own R4 DS Box. But you'll notice that once you open the box, the contents of the box are identical to the M3 DS Simply, you even get the same light blue colored keychain / carry case that comes with the M3 DS simply. You get everything you need, right out of the box.Play MP3s and MoviesBy using the excellent program Moonshell (Which comes bundled with the R4 and M3 DS Simply) you can turn your DS into a portable media player, able to play MP3s and DPG movie files.The NDS Fire Card also provides extra features, such as the ability to download skins. This lets you personalize your DS screen and further customize it with Photoshop. Other storage devices, such as the R4 DS, do not have these perks, leaving you with a plain, boring interface. If these added bonuses are important to you, then you'll want to get the NDS Fire Card.For a real time-saver, the Nintendo DS Fire Card offers the easiest game selection available. The touch menu allows you to browse through your games quickly to get to the one you feel like playing. Other devices, like the DSTT, have major disadvantages with this, including an inability to alphabetize your list of games and a lack of a simple folder browser.The R4DS is not illegal (you can buy them from Amazon), but Nintendo wish it was. Video game pirates use the R4DS to play games they do not own legally. Owners of the R4DS are urged not to take advantage of this and Nintendo are fighting to stop the sale of the product. The long-term effects of piracy are a weaker gaming industry and therefore fewer games and games of a lower quality.
