1. Download the latest firmware v140 and copy firmware.bin to the MicroSD card (the format must be FAT32). Insert the micro SD to the sky3ds + cartridge, connect the USB cable to the computer and sky3ds +, when the red LED flashes for about 30 seconds, the Sky3DS PLUS card is now updated.
2. Insert sky3ds + and any original 3DS cartridge into the two skydock adapter slots. Connect the USB cable to the computer and sky3ds +. The blue light flashes, then the savekeys.txt file appears in the micro SD ( savekeys.txt is for saving the header of the original online 3DS cartridge games.)
3. Press the orange button of sky3ds +, the red light will flash and the two .cfg and .sav files will appear in the micro SD. That means the skydock adapter is reading the original cartridge header and the game backups.
4. Press the orange button d sky3ds +, when the red light flashes for a few seconds, it turns into green light. When you turn off the light, the .3ds rooms of the original cartridge will remain in the microSD. (The duration of blinking light depends on the size of the game, so be patient, if the cable is unplugged, the game will not work.)
