I've been looking for a second copy of Animal Crossing cheap (ie, less than ?15 in total ideally >.<) to get some cycling done and stuff, but they're all ?25+ xD Then I remembered we have SD cards!! Never really understood their use in a DS other than photos and stuff... But are save files stored on there? If so I can buy a cheap SD card and use that to have multiple towns on ACNL, as well as other games. I'm not sure how much is saved to the game card, and I may be sounding super nooby and old, but I've only ever used memory cards xD GameBoy games saved to the cartridge, but we didn't have SD cards like that then! Has it changed? Or do I still need a second copy of the game? x3x
