Twenty years later and I still struggle to get past level 9. ;)
Tomorrow I think I'll tackle Super Marioland 2. A classic from 1992.
I gotta say--- there's something to be said for electronic devices that take 4 AA batteries. None of these cables and chargers that change with each new model.
As long as there are AA batteries in the world, there will be working Game Boys. And that makes me happy.
