My friend wants to buy a 3ds flascard

Last time i remembered there was no flashcard that supports or plays 3ds games. Is this still true?This is the flashcard he was planning to buy,http://www.r43ds.org/products/R4-3DS-RTS.html

theres a couple that do on early 3ds firmware versions

There are at least two flash carts (Gateway 3DS, the R4i Gold 3DS edition and MT-card http://www.r4flashcart.com/21-mt-card-first-3ds-multi-rom-flash-card.html MT card is the best out there) that work with 3DS roms on the 3DS right now, but your 3DS has to be on software ver. 4.1 to ver.4.5.

his Version is 7.1 so it wont work? or he will have to wait until they crack 7. firmware?
