I'm sure everyone's probably stumbled across the
hilariously bad bootleg version of Pokémon Crystal with a... very bad translation. So bad, it even makes Vast Fame's translations look good.
Anyway, I mention this because there are not one but
two Let's Plays of it out there now.

(And yes, this thing actually exists on cartridges-- I can't find it anymore, but I know I've seen a YouTube video where someone tried to play it on a Game Boy Player. Even the "this only works on GBC" message was in utterly nonsensical Engrish.)
Edit: A third Let's Play! Wow, it's like everyone decided to play this same bootleg this month.
