We used to play Battletoads with my friend in a 2-player-mode and with daily playing we managed to beat that piece of frustrating video game entertainment. After we did it, we decided to find the SNES version and try to beat that also. And guess what, we did it :)
I don't think it's really the hardest game ever.
The thing with those games is that they are so fun to play that the frustrating factor doesn't get that much on the way. For example, I think Ninja Gaiden (Shadow Warriors) is something I don't really want to play much because it's too frustrating and hard.
damn i remember the battletoads...i used to love this game...i hada hard time passing the one where ur flying thry this spikey CAVE and it goes down quick :(
it seems like I remember the battletoads and double dragon game being easier than when the battletoads were solo. Also Back to the Future II and III was a hard game.
Fester's Quest is one of the hardest for the NES. I can't get past a few screen lengths because you get three hits from an enemy and one life before the game is over.
Apparently the makers of Fester's Quest thought it was hard, too. They had a competition where if you beat the game, you send in a picture of your TV with the ending. I sent it in but didn't win anything at all. I thought that game was very easy, myself. Battletoads, though, was sooo hard. At least when you were single player and got to the rocket sled thingies. Don't think I ever made it past it. Been years since I tried. NInja Gaiden, part 1, was easy to me. UNTIL the end boss. I NEvER beat him. EVER. And it sent you all the way back to the beginning of the level. Screw that.
