Where to buy R4i-sdhc rts 3ds card?

ANTIOCH, Calif. - Feb. 11, 2014 - PRLog -- A few days ago, Nintendo released the newest 3ds 7.1.0-15 system firmare, r4i-sdhc 3ds rts is one of 3ds flashcarts that bypassed the new 3ds update directly, the team behind the r4i-sdhc 3ds card is normally incredibly quick to update when Nintendo releases a patch that blocks flashcarts, meaning that your r4i-sdhc 3ds card will be back up pretty soon when everybody elseis blocked or forced to wait a long time for a fix patch.
And the r4i-sdhc 3ds rts card is very easy to use, all you need to do is to download the latest kernel from the official website download page, currently, the newest r4i-sdhc 3ds rts card kernel is version 1.77b, which was released weeks ago, some game bugs have been fixed and more new games have been added. You'll want to unzip the compressed kernel file, copy and paste all the contents in the kernel folder into the root of your microsd card, and insert the microsd card to the r4i-sdhc 3ds rts card, at last, insert them to the slot of your 3ds/dsi/ds console and done. From what I can gather, the setup steps of the other 3ds flashcarts seem to be all the same.
I just bought my r4i-sdhc 3ds rts card from this seller http://www.r4flashcart.com/9-r4i-sdhc-3ds-rts-flashcart-f... that's the cheapest place i can find, the r4i-sdhc card came pre-flashed to work with my 3ds 7.1 out of the box, shipping was extremely fast, most importantly, shipped from United States.
