Not sure if this is it, its from around the right era and was a very popular series of handhelds here in the uk, i remember owning 3 of them myself from grandstand. There is a bit where you have to grab a sword to kill medusa, that and the general monster theme made me think of this one, if i am wrong i am sorry hehe
