1636 Pokemon Fire Red Squirrels

Review: The "Meme" That Saved the Franchise for Many

If you have ever downloaded a Game Boy Advance emulator on your phone, computer, or PSP, you have almost certainly encountered "1636 - Pokémon FireRed (Squirrels)." It is, without a doubt, the most ubiquitous ROM of the Pokémon franchise in existence.

But what actually is it? Is it a hack? A mod? And why is a squirrel on the title screen?

8. Conclusion

The 1636 Pokémon FireRed Squirrels ROM is a fascinating artifact of early ROM-hacking history. It represents the ambition of a fan wanting to bridge the gap between the GBA and DS eras, but it also serves as a textbook example of why game engine limitations cannot be bypassed simply by shoving new data into a game's code.

Today, it is played almost exclusively by YouTubers and Twitch streamers for "shitpost" content, utilizing the broken sprites, hilarious translation errors, and unpredictable glitches for comedic effect. It is not a game to be played for a genuine Pokémon experience.

1636 - Pokemon Fire Red (U)(Squirrels) is a specific digital copy (ROM) of Pokémon FireRed version 1.0 for the GameBoy Advance. In the ROM-hacking community, it is considered the industry standard "clean" base file required to create popular fan-made games like Pokémon Radical Red and Pokémon Unbound. Why This Specific File Matters

Hacking Standard: Most ROM hacks are designed as "patches" that only work when applied to this specific version (v1.0) because later versions (like v1.1) have different internal memory addresses that break the hacks.

Integrity: The "Squirrels" tag refers to the original group or individual who "dumped" (copied) the game from a physical cartridge. It is widely trusted by developers for being a 1:1 accurate copy of the original retail game.

Verification: To ensure you have the correct, uncorrupted version for patching, hackers often check its CRC32 hex code, which should be DD88761C. Common Uses

If you have this file, you are likely looking to patch it into one of these popular fan games:

Pokémon Radical Red: A difficult, feature-rich overhaul including Pokémon from all nine generations.

Pokémon Unbound: A completely new story and region built on the FireRed engine.

Pokémon Clover: Another major fan-made game that requires this specific base ROM.

Note on Legality: Downloading this file from the internet is generally considered software piracy. Community members typically recommend finding it on sites like the Internet Archive if you do not own the original cartridge to dump yourself.

The Fan Theory

The most popular fan theory ties the 1636 squirrels to Professor Oak’s unused email system in Fire Red. In the game’s debug strings, there’s a message: “Come see my new discovery — the squirrels of Route 22 are evolving!” Route 22, of course, is the competitive battleground near the Indigo Plateau, usually devoid of any special wildlife.

Some believe the squirrels were meant to evolve via a now-deleted “Nut Harvest” mechanic — similar to Berry farming in Ruby/Sapphire — which would have let players grow acorns into evolution items. Had it shipped, Fire Red might have introduced Kanto’s first cross-generational evolution: Acornimbus evolving into Heli-squirrel (Electric/Flying) with the Thunderstone.

The Verdict

Score: 9/10 (As a Game) | 10/10 (As a Cultural Artifact)

If you want to play Pokémon FireRed today, you should technically seek a verified "clean" dump. But there is a charm to the Squirrels version that cannot be ignored. It represents the golden age of emulation. It is the version that introduced millions of players to Kanto when they couldn't afford the actual cartridge.

It is stable, it is compatible with every cheat code on the internet, and seeing that squirrel pop up before the Game Freak logo feels like coming home.

Cons:

Recommendation: If you are looking to replay Gen 1, or if you want to use a Randomizer, download the "1636 Squirrels" version. It just works.

The Discovery

While sifting through hexadecimal offsets in the game’s ROM, a modder known as SquintyPikachu found a string of orphaned code at memory address 0x1636. Tucked between pointers for Route 4 and Mt. Moon’s tile behaviors was an unused species table labeled SQDATA. Inside: three Pokémon — Squirruff, Chestnutail, and Acornimbus — each with placeholder cries, move sets, and even a rumored link to an event never activated.

The kicker? Their types are pure Normal, Grass/Normal, and Flying/Normal — making them early-game Route 1 fodder. But their designs, pieced together from leftover sprite fragments, show fluffy squirrels with leaf-like tails, acorn cheek pouches, and a curious item: the Hard Nut, which acts like a one-time Berry but triggers a speed boost when thrown.

1. The “1636” Number

Why “1636”?

The number isn’t random. In the original Japanese Fire Red build, 1636 was intended as the Pokédex index range for “regional small mammal” clones (after Rattata and Sentret). But the squirrel trio was cut due to memory limitations on the 256KB save file — and because, according to an alleged internal memo from Game Freak (never confirmed), the devs felt three Normal-type rodents per generation was “one too many.”

Still, remnants remain. If you use a GameShark code 82023F00 1636 in Fire Red, the game crashes — but not before flashing a single frame of a brown, bushy-tailed sprite. Speedrunners have since dubbed this the “Squirrel Glitch,” and some TAS (tool-assisted speedrun) creators have used it to warp directly to the Hall of Fame.

Conclusion: Separating Nut from Fiction

The keyword "1636 Pokemon Fire Red Squirrels" is a perfect example of niche internet culture colliding with retro gaming. It is not official Pokemon canon. It has zero presence in the original Fire Red game data. However, it lives on as:
