Maybe its Nintendo plan...this Crown 3DS...some card for 3ds rom and we all just waiting and nothing happened and on the end we say its impossible to do anything...ok well we buy a game and Nintendo win :)
I open this file with winrar and its not open...some error...any other program maybe?!. So just copy this 3ds rom-loader to the flash card. When I put the card on the 3ds just start this program and then?...find maybe the 3dsroms in micro sd and this is it...an then play 3ds rom?
