I've been doing a lot of research on the flashcarts currently out and the features they offer and they all seem like a waste of money. Years ago for 14$ I got a "fake" r4 that came with a 2gb SD card that can play any rom and the save files could be edited; but the DS was a simple device. Currently all these flashcarts let you do is give you maybe 10% more functionality than you currently get with the 3ds and feel cool that you're using modded shit. Yea you can dump data via them, but that's all they're good for, and only people that benefit from that are people that want to further their knowledge of the 3DS. With 3ds firmwares and update systems, for the average consumer current flashcarts (as of 3/24/14) do not provide much, other than false hope of someday being back to their former glory.
