I have a request. For those who are interested... You CAN back up sm4sh 3DS replays. Go into the SD card. Go to Nintendo 3DS > 000000 > extdata > 000000 > 1b1c [needs checking, E versions only] My proposal is this. Make a 3DS homebrew app that can extract these and import them. Basicially a backup and restore tool. Think SpecialliseMii but for replays. Thankyou. This is my first ever post.
