not useful if you want only to play with free game.well.. GW ended for me but not that I don't think it's pratic ... I mean, it's not needed anymore but we can't say that it's not useful , right? xD
But since I was without a 3DS I borrowed my GW to a friend, and he got his packback stolen, with the 3DS, my GW and a lot of his stuff .3.
Since they are very expensive here and still without a 3DS I don't plan getting a new one.
What ?Game Boy Advance games?
It's a tool who can extract the emunand from the sd card.
