I have a 3ds which is running the newest firmware (9.9.0-26) and I want to buy a flashcard for it. I had one, but it was a clone, and they stopped supporting the flashcard, so I want to buy a proper flashcard, which is not a clone. It doesn't have to play 3ds games (I thought those that can are really expensive now?), but I want one that will (for as long as they can) be able to run even if I get an software update. I do have a lot of bought 3ds games, also from the e-shop, so the updates are something I really have to do. Which one is recommended?
In that case, the r4i series such as R4i Gold 3ds, r4i sdhc dual core, r4i sdhc silver rts lite, r4i gold pro and r4i sdhc rts cards may be quite suitable for you. They support to play ds games on 3ds console with newer firmware. What's more, their prices are low.
Now the question should be What flashcard for 3ds v10.1.0-27 and the answers is liking the upper too. JUST PLUS sky3ds card which supports 3ds games on 3ds/new 3ds 10.1 firmware.
