I HAVE GOOD NEWS EVERYONE (read that in professor Farnsworth voice (futurama) I have retrieved my cartridge, I managed to find a wire coat hanger so I untwisted it and made it into a long line, I stuck a load of duct tape on the end and sort of went fishing with it...the bad news, I cleaned it as best I could and dried it with a towel, but for some reason my 3DS isn't recognizing the cartridge is actually in my 3DS, I will keep trying and see if it eventually works, but If it still isn't working by the morning, I don't know what else I can do.
