It powers on and still works, but seems to have that problem that one eye isn’t working. I read, that it is a common problem with the glue on one of the cables.
I have no idea how much it’s still worth, but would love if someone bought it who knows how to fix it.
It includes the Joypad, the stand (which has a minor fracture in the middle, but still works), the battery case, the power adapter case and five games:
Wario Land, Funky Bowling, Galactic Pinball, Baseball and Mario’s Tennis.
