I used to like a website called TRsRockin.com which documented a whole lot of Pokemon glitches. The closest thing nowadays is "TheZZAZZGlitch's" videos on Youtube.

Back in the day, people used to go wild with these glitches. It's pretty easy to get Pokémon Red and Blue to explode in entertaining ways, and it gets unhinged really d*** quick
Just seeing a Missingno. causes the game to overwrite part of your save data, which means that viewing your Hall of Fame after doing that will cause it to glitch out in some really intense ways. When I was a kid with a Game Boy Color, I used to try to listen to some of the glitched noises it'd make in the dark in the bathroom of my grandma's house. I would nope out pretty quick because of how unsettling it could get
It's actually so lucky that the only save data Missingno corrupts is the Hall of Fame and not something actually important.
