Good work! I just did a google search of hardest ever games, and feel quite proud of myself too. I loved "Link to the past" (Zelda 2), but having played it recentlyish on my phone (where yu can save at ANY point, so it's pretty easy), I am impressed that I finished it as a kid. Also, I LOVED the Dizzy games, and have been reminded how hard Treasure Island Dizzy was, as you had no extra lives, touch one thing and it was all over!
