I've managed to finish Life Force (NES) in one life, Megaman 2 in one life, and I agree that finishing Blaster Master at all is pretty good. (Did it twice)

The best I've ever done at 1943 is 945,000. I want to break 1,000,000, but I now magically suck at the game and I can't even defeat the mission 4 boss! I don't know what's wrong with me...
