Yeah, you need to buy a updated flashcart which can work on DSI V1.44, i recommend if you can just choose one of these three cards. R4i gold 3ds, Acekard 2i, DStwo, DStwo is the best and also the most expensive, i dont recommend unless you want to play gba games or enjoy other features. and i personally love R4i gold 3ds more. acekard 2i is also good card, but this card recently updates very slow, they still can not work on the latest 3DS firmware. many guys are unpleasure with it now. But r4i gold 3ds updates very quick and wood firmware is awesome. And here is the site i recommend, Buy acekard 2i, r4i gold 3ds, dstwo, ace3ds flashcards for low prices-dsflashcart.com you can find the site review here: http://www.wiihacks.com/recommended-...hcart-com.html
You'll need to 'flash' your R4i to be compatible with the latest firmwares from nintendo. There are detailed instructions for downloading the kernel, flashing your R4i, and loading the newest R4i firmware onto your micro sd card on the manufacturer's website.
You can buy it fully set up and ready to go from w w w . b i t d a r t . c o m
