buying a used game that had the cheat codes written down in the manual felt like a gift from god lol
not rly a specific moment but man i remember when cheat codes were the big thing in games, i'd almost always look them up after playing a bit to see if there's any and then have a blast with em lol
not particularly a cheat code but i remember memorizing the entire loving password for 30k bells in gamecube animal crossing when i was a kidfun stuff
not particularly a password but i remember stealing the declaration of independence to decode it and find the treasure within
