Oh password screens. The bane of the retro gamer. Now a days if you're emulating, you can use save states to save your progress, but back then if your game didn't have battery backup which made the carts more expensive, or your system was a PC Engine without a Tennokoe Bank then you're filling out notebooks with these monstrosities and then entering them back into the game hoping you wrote them down correctly and that you can read your own handwriting. What are some absolute dog shit password screens you've seen out there? I'm very curious. Post 2 will have some of the stranger ones.
Shoutouts to G.I. Joe: The Atlantis Factor for their sudoku like password screen. Then we have James Pond 3/Super James Pond II for the SNES which uses 32 different symbols which all can be 1 of 4 colors. Then there's the PAL version of Dragon's Lair also for the SNES. Trust me that is a password screen, the below video will explain it all but tldr password screen is a ingame level with a timer and you're fighting with underwater physics. Finally here's Cheesy for PS1, also PAL. While it looks inoffensive, trying to actually enter a password will see you constantly zooming pass the character you wanted because for some reason the controls here are super sensitive and erratic.
