Yep. Remember that wwylele's PR is in development. He might make the QR Limit to more than 240p(Regular 3DS Screen).
I need to try crop the QR code photo again if the citra's camera cannot aim it,now i know how to resize the QR code photo for making citra easier to scan Just make sure the QR code is at the middle , and then ,the smaller QR code picture,the easier the citra camera can scan it without any trouble,i had try to scan games other than pokemons as well,it works as well ! I looking forward to wifi implementation ,maybe in this year as well...
