Always be careful when using the word "noob", you might embarrass yourself.
"Buried Alive" is a creepypasta. It's a scary story that sometimes people think of as real facts, but actually someone made them up because they are creepy and interesting. (Like "Pokémon Lost Silver", a creepypasta that got its own fanmade game.)
There never was such a thing as "Buried Alive" that Game developers wanted to add in the japanese game, because you would find the sprite of it in the source code. You should also find it with the help of Gameshark, but since you can't, it will stay just a story forever. (I admit that I even did that myself with RBY to prove a friend wrong who also thought this story was real.) I have never played Pokémon Green, but that doesn't matter because all Buried Alive Internet Videos contain RBY anyway, but those are romhacks. But very good romhacks!
I recommend watching the Buried Alive video though and playing Pokémon Lost Silver if you like creepypastas so much that you'd like them to be true. :)
