long time lurker first post lol metroid on the NES uses passwords instead of battery saves. The most famous one is: JUSTIN BAILEY followed by dashes to fill teh rest (written as 'JUSTIN BAILEY ------ ------').
Enter it and you start with Samus out of her power suit, in a leotard, with various items already unlocked.
The fun twist: its not a hand-made cheat. The password system encodes ur game state, and that string just happens to decode to a valid state with the suitless flag set. People found it and it spread like wildfire through magazines and playgrounds. im about to throw this thing out the window lol
