Now this doesnt have a label on but i think it is a supercard, if i am arong could someone tell me otherwise.
It comes with the cable that you need to plug it into gameboy.
I havent used it myself as i have another cartridge that does the same job and this is a spare one.
After £25 because these are hard to get in the UK and i paid £30 for one on ebay.
