Inspired by Pokemon GO, my housemates and I have jumped back into handheld console versions of Pokemon. Our plan was to buy four games on cartridge (Pokemon X, Y, OR and AS) and buy two 3DSes to share between the bunch of us, since buying a handheld each seemed ridiculous.
I'm having trouble finding out how the saves work. It looks like they're not kept on the cartridge or the SD card, and perhaps they're on the onboard memory? Is there a way to move them from machine to machine; that is, can the four of us play on whichever machine's available and trade/battle each other or will we need 4 3DSes
