Popeye

Fry until the screen rolls. Wait until it stops (rolling) and the game will start automatically with 255 lives.

Get nine or more hearts, and then purposely die. Once you start your next life, you go to the right off of the ledge, immediately get the spinach and hit Bluto/Brutus. If you do it quickly, your score will become 155,120 (or thereabouts), and if you have died twice already, your score will be 144,120 (or something like that).

Start playing and then hold down the reset button--the music will play about an octave lower. Seems only to work on the older 2600 console, and not on the 2600jr and 7800.
