In the world of Pokémon ROM hacking, 1986 - Pokemon Emerald (U)(TrashMan)
So, why 1986?
The region of Hoenn is distorted. Littleroot Town's lab has a broken computer with a terminal that displays ASCII art of a Trash Can. Professor Birch is replaced by a sprite called "Old Man Utrash," who speaks in binary. If you translate the binary, it reads: "Do not catch them all. Let them rot."
Let’s get one thing straight: Pokémon didn’t exist in 1986. The first Pokémon games launched in Japan in 1996. Pokémon Emerald came out in 2004. So when a mysterious ROM surfaced last month labeled , the emulation community lost its collective mind.
