If you are playing this specific ROM, you are playing the vanilla Pokémon FireRed story. For a Game Boy Advance game released in 2004, the story is highly regarded for several reasons:
The "Hero's Journey" Done Right FireRed is a remake of the original Red/Blue, but it adds much-needed depth. It is a classic, stripped-down hero's journey. Unlike modern Pokémon games which can get bogged down in cutscenes and prophecies, FireRed keeps it simple:
The Rival Dynamic This is where FireRed’s story shines. Your rival (usually called Blue/Gary) is the perfect antagonist. He is always one step ahead of you.
World-Building over Narrative The "story" in FireRed isn't just about the text on the screen; it's about the world. The Sevii Islands (added in this version) expand the lore, connecting the Kanto region to the Johto region and adding post-game content that was missing from the original Red/Blue. It makes the world feel lived-in.
Team Rocket Team Rocket in this game is portrayed as a genuine crime syndicate rather than a goofy evil team trying to destroy the world. They take over a company (Silph Co.) and a city (Saffron), and you, a child, have to liberate them. It feels gritty by Pokémon standards.
Without a known author, build date, or source repository, “1636 Pokémon Fire Red - U-- Squirrels” sits in a gray area between ROM hack and digital folk art. It is simultaneously broken and functional, silly and obsessive, funny and deeply unnerving.
If you stumble across a copy, back it up. Play it. Let the chittering consume you.
And whatever you do—don’t nickname your rival anything other than “CHITTER.”
The squirrels are watching.
