I had Zelda on GameBoy. Was the boss (think it was a genie of some kind?) where you had to throw the bottle against a wall to damage him. One sitting I kept on just missing the wall and eventually punched and broke the screen of my beloved handheld... more rage than quit I suppose 
EDIT: Sorry, forgot to respond to OT - you should in no way feel bad. The younger generation need to learn "normal" is the way you're meant to play it. "Easy" is for drunken nights or fond replays!
