What's the pre-flashed 3ds card work for 3DS V8.0.0-18?

July 7th 2014 the Nintendo rolled out a new system update for its family of 3DS handhelds to version 8.0.0-18. This change doesn’t introduce any noticeable revolution—just for standard stability update, which usually means that Nintendo has quietly added checks to block new hacking methods or streamlined the performance of certain apps like the eShop.

Then pay attention to  a new problem that which pre-flashed card can support 3DS 8.0.0-18?
