TMNT was pretty hard with that damn dam but it was doable if you practiced. I think Battletoads and Ghouls and Ghosts are some of the hardest, most brutal games ever made.

I don't remember being stuck on any Castlevania games but I might've read Nintendo power to figure some stuff out, I don't remember. I think my friends and I were like Tensers situation. We just played for hours and hours until we figured things out, it was part of the fun.
I know we figured out the duping secret in FF2(us) on our own. I remember accidentally doing it and scrambling to figure out how I got it to work.
