Double Dragon for Atari 7800.....now how in the hell can anyone expect to beat that game? I litterally played it about 6 hours straight in order to pass the first stage....and that was a couple months ago!
I think it was Double Dragon II (possible I), on an ancient PC. The objective is to rescue some girl, kicking the living daylights out of everything on your way there. I made it all the way to the final screen. Finished the end boss, and started walking towards the girl... and the game locked up on me.
Now *that* is annoying: completely finishing a game, but not really.
