What Is a Nintendo DS R4 Card?

• Answer:

  The Nintendo Double-Screen (DS) is a unique hand-held gaming console because there are so many products that can increase its functionality. The DS R4 card, developed by R4, is one of those products. The R4 can add extra features to a DS such as cheat codes to official games and the ability to play user-designed games. Shape The R4 card is square-shaped and roughly one square inch in size, just like a DS game car. This shape allows the card to be easily inserted into any DS game slot. However, the R4 card has a small slot in which a Mini-SD card can be inserted. The data on this card can be accessed by the DS. Compatibility In order to use the R4 card properly, you will need access to the Mini-SD card that goes into the R4 and a computer that can read the mini cards. If you do not have a Mini-SD card slot on your computer, a USB memory card reader has to be used to connect the card to your computer. Games/Other Uses The R4 card gives DS gamers the ability to play home-made (or "Homebrew") games on the machine. These games are made by gamers and can be placed on and downloaded from any homebrew DS game site. Ebooks can be downloaded to an R4 card and read on the DS as well, provided the eBook file is placed in the proper folder on the Mini-SD card. The DS can also adopt a large number of themes from the R4 card such as menu color, menu icons, and menu text. Action Replay "Action Replay" cheats are codes that can be inserted into certain games to give the player an edge in said games, such as infinite lives or invincibility. The R4 card makes it easy to add Action Replay cheats to the DS games. The R4 card's menu is similar to the Action Replay menu, so players can select or delete codes, add codes, and manipulate code lists. Product Information Since the R4 card allows gamers to use the DS for something other than its original purpose, Nintendo does not encourage or promote them. However, using the card is not illegal. The card is generally available online for $20 (as of June 2010).
