R4 Card

The R4 Card comes in two versions; the original R4DS and later R4 SDHC. The R4DS or R4 DS as it is also known was the first R4 device to be released by the R4DS.com team and allows users of the Nintendo DS and DS lite consoles to add a Micro SD card to their consoles. Micro SD cards come capacities up to 2GB which at the time was impressive but no with new flash card technology Micro SDHC cards have been released. This is where the R4 SDHC card comes in, the R4-SDHC supports both Micro SD and SDHC memory cards meaning you can store up to an amazing 32GB of data on a single memory card, roughly the same size as a penny coin. To begin using the R4 you will need either a Micro SD or SDHC memory card which we offer bundled with our cards.

R4i Card

The R4i Card was released shortly after the release of the Nintendo Dsi console. With this new console the previous R4 cards were rendered useless so a new card was needed. The R4i-SDHC.com team who had made the previous R4 SDHC cards released the R4i SDHC which works with the DSi and DSi XL consoles allowing users to experience all the great benefits of the R4 but now on the DSi and DSi XL. The R4i-SDHC card works with a wide range of file formats meaning you can store music, movies, photos, videos and even eBooks for playback on the go. The R4i card massively increases the capabilities of your Dsi console for a low price and this has made it such a huge success.


The R4i-SDHC.com released the R4i SDHC to work the DSi and later the DSi XL console, these new consoles come with constant firmware updates from the development team in Nintendo and to stay up to date with these the R4i-SDHC team has their own dedicated developement team which offers constant updates and excellent user interface. This is the reason why the R4i Card has become the number one flash card for the DSi console, offering the best in development and customer support, this ofcourse is combined with the experience from a team that also designed the R4 SDHC range of cards.

Thanks to advances in current Nintendo DS flash cartridge technology, many innovative features have now simplified and improved people's gaming needs beyond the original capabilities of the handheld console.

Like the original R4DS for the Nintendo DS and DS Lite, the Nintendo R4i SDHC for DSi bought people even more features on just a single flash card.

The next generation flash card

The Nintendo R4i SDHC is actually the latest in R4 flash cards for the Nintendo DS console family. It's already, in fact, considered the next generation Slot 1 flash card. In contrast to its previous versions, the Nintendo R4i SDHC was made 'specifically to address providing the same open features and functions to the Nintendo DSi system.'

The main difference between the Nintendo R4i SDHC and other R4i cards is that the latest version of the Nintendo R4i SDHC accepts commonly used microSDHC cards. The updated Nintendo 3DS compatible version of this card is now sold under the name R4i 3DS and R4i SDHC 3DS—the only difference being that this version supports the Nintendo 3DS.

The Nintendo R4i SDHC, on the other hand, provides support for all available Nintendo DS models, naturally under various editions. As an example, there are models made to fit the original Nintendo DS, while there are others that exclusively fit the Nintendo DSi.

What's new in the Nintendo R4i SDHC

The best thing about the R4i SDHC is its fast loading times, in addition to its compatibility with many Nintendo DS models, including the latest Nintendo DSi XL (Nintendo DSi LL). There's alternative model flashcards like the DSTT, though they're considered less efficient when compared to the R4i SDHC.

SDHC cards improved the performance of current R4i cards. Some of the improvements stem from factors like its native formats, storage capacity, multilingual settings, power saving functions and a new user friendly interface. In addition to its native compatibility with all Nintendo DS games, it also supports settings for soft-resets and various cheat codes.

Thanks to this, people who start using the R4i SDHC have the ability to get more out of their Nintendo DS console. People not only can play their games on the go without having to worry about individual cartridges, but can also listen to music and watch movies anytime.

Other characteristics of the newly revamped R4i SDHC include automated save-type detection, direct microSD card saving and support for download play, the DS Browser and various Wi-Fi games. Moonshell support is also included, a media player that's perhaps the most popular DS homebrew app. The app can play music and convert videos to AVI, MP4 and the proprietary NDS DPG video format.

The R4i SDHC is truly an excellent multimedia tool that can get the best out of the Nintendo DS hardware. The newest iteration of the R4i SDHC just pulls much more out of the console with its higher decoding performance and much better picture quality.
