R4 cards are new devices for Nintendo DS units. The R4 card first came out in 2007 and since then no Nintendo DS can be found without one. The R4 card serves as a tool that promotes functionality and amazing features. The Nintendo DS is built without memory storage, which is why the R4 card is not just an accessory, but a necessity. It allows you to not just play high memory games but store multiple games files at the same time.

It also enables your Nintendo DS to read word file, so you can also read eBook using your gaming console. One of the best features of R4 card is that it allows users to the console like you would with your iPod or even iPod touch, you can store as many songs, eBook files, and high memory games all at once.

In case you still don’t have one, an R4 card is of the same size as the regular Nintendo game cartridge. The only difference is that they have a slot on the back of the card where the Micro SD card is inserted. Some R4 card even supports up to 32 GB micro SD and HC cards, like the R4 SDHC and R4i SDHC.

On the top of the R4 card you would notice the slot, it uses a push spring mechanism to lock the Micro SD in place. A simple push on the card the Micro SD will come out easily. However the R4 team realized that the spring mechanism causes the entire card system to be ruined. The R4 card production was said to have affected by 5%. The production of the spring mechanism continued for less than a year and then a new model came into picture. The R2V2 card replaced the R4 but then another card was launched the R4 SDHC and they became the most popular R4 card today. More cards were launched but the R4 SDHC and the R4i SDHC are the best ones in the market.

The Micro SD is where all the applications, games, and firmware are stored while the R4 card serves as the adapter. Once you’ve placed the Micro SD in the R4 cartridge, you will then see a menu on your screen upon booting up. The menu allows you to choose the application that you wish to use. You can download multiple of homebrew games and store them at once in your r4 card. You can choose from multiple games stored into your R4 card, and play as you wish, no need to keep changing your cartridge. This would especially be ideal when you are on a trip.
