In this day and age of knock off and clone cards that sport the R4 sticker, but have nothing to do with being an official or original R4, it is more important than ever to ensure that you double check and make sure that the card you're buying is from an official source. Most consumers in the market for a card don't realize that they have purchased a fake or knock off version right away. In fact, they tend to find out when they try to update their cards to match the new version of the updates for the 3DS, only to discover that these so called real r4 sellers, were actually just fly by night operators - and there's no update available for their card at all.
When you purchase your R4 3DS Card from the official store at www.r43ds.org, you can rest easy knowing that you are buying a card that has been supported since the very first 3DS console was released. An official card ensures that you get the latest firmware kernel updates, as quickly as possible, each time that the Nintendo 3DS is updated. In fact, with an original and authentic card, customers find that they don't always have to have a new firmware update, simply because the R4 3DS works out of the box with certain OS updates.
With the release of the newest 3DS v4.0.07 update, the r4 team has released their new 1.29 firmware kernel for the RTS (Real Time Save) version of their card. This new kernel ensures compatibility with the latest 4.0.07 versions of 3DS systems. As well, the card is also compatible with the new 1.44 DSi and Nintendo DSi XL updates, both included in this v1.29 of the kernel.
http://www.r43ds.org has also added better compatibility for all emulators and homebrew as well in this new kernel. Homebrew games and developers alike will find that more of what they love can now be loaded and played on their consoles.
To download the latest firmware visit the official r43ds.org firmware download section and download the firmware in the language of your preference. Installing the firmware is a snap. Simply copy over the firmware files to the micro SD and you are all set.
