Ahh, the good ole days (when games beat the shit out of you)

[Toast]

Blaster Master was really hard. I never did beat that game.

I remember the absolute brutality of that crab boss that would slide back and forth and fill the entire screen with bubbles of death. FPS would drop to about 2, and you just had to deal with it.

Castlevania for NES was also a beatdown.
