I found these data carts at a store where I found some semi-rare games. The lady at the store told me that the carts were used for backup purposes. I checked on the net on the kinds of hardware that can read the carts and found hardware over $1000. h: The data carts are labeled M2, and I have three of them, each numbered 1-3. I currently have no idea what are on these carts :shrug:, and could contain useless crap, so don't expect much. Well, here are some pics!
