1636 Pokemon Fire Red Squirrels Upd
Some internet stories invent “lost Pokémon” with high numbers (like 1636) and silly names (“Squirrels”) to seem eerie. The “FireRed Squirrels” might be a meme where players claim entering 1636 in a cheat device spawns a demonic squirrel that crashes the game.
The “1636 Pokémon Fire Red Squirrels UPD” is not a hoax, nor a random internet gibberish. It is a properly documented, mechanically fascinating, and thoroughly weird glitch that reveals the fragile beauty of Game Boy Advance programming. It stands as a testament to the dedication of glitch hunters who, years after a game’s release, continue to find squirrels where no squirrels should ever be.
If you own an original v1.0 Fire Red cartridge, do not try this at home. But on an emulator? Go ahead. Chase those digital rodents.

It is important to clarify upfront: there is no official “1636 Pokémon Fire Red Squirrels UPD” patch, ROM hack, or game release. The keyword appears to be a fragment or a search string that has gained traction in niche online communities, likely a combination of a random number, a game title, an animal, and an abbreviation for “update.” However, given the creativity of the Pokémon ROM hacking community, this phrase can be interpreted and built upon as a hypothetical or a request for a mod idea. Some internet stories invent “lost Pokémon” with high
Below is a deep-dive article exploring what such a phrase could mean, how it relates to Pokémon Fire Red, the concept of “Squirrels” in hacks, and what “UPD 1636” might signify in the context of fan-made games.
Glitch analyst “Chickasaur” (in a 2010 deep-dive) explained that 0x1636 is a pointer in the game’s dynamic encounter data. By performing the glitch sequence, players cause a buffer underflow that shifts the game’s random encounter lookup table by 1,636 bytes. That shift lands the game in a region of memory reserved for PC box names and player nickname data. When the game reads that as wild Pokémon data, it interprets random characters as species IDs.
Sentret’s hexadecimal ID is 0x161 (353 decimal). The glitch’s offset causes the game to misread a nearby memory byte as 0x163, which then calls Sentret but with corrupted level and move data. The “squirrels” label stuck because early players saw the tail and thought of rodents.
In the world of Pokémon Fire Red (a 2004 remake of the original Red Version on Game Boy Advance), numbers typically refer to one of three things:
If you’ve stumbled across the search term “1636 Pokémon Fire Red Squirrels upd” , you’re likely confused, intrigued, or hoping to find a bizarre new ROM hack. You are not alone. This string of characters has appeared in forum logs, Discord bots, and search engine queries without a clear source. Let’s break it down piece by piece and then construct what this could be—because in the world of Pokémon hacking, obscure keywords often lead to hidden gems. Have you encountered the 1636 glitch
If you’ve stumbled upon the phrase “1636 Pokémon FireRed squirrels” while browsing forums, ROM hack lists, or glitch videos, you’re not alone. This odd combination of numbers and words has puzzled fans. While there is no official Pokémon named “Squirrel” in FireRed/LeafGreen, several theories explain where this idea comes from.
In Gen 3 games, attempting to cheat or corrupt data can produce glitch Pokémon with hexadecimal IDs. When converted to decimal, some reach numbers like 1636. These glitchmons often have scrambled names, one of which might look like “Squirrels” if the font corrupts.
Example:
Hex 0x664 = decimal 1636. In FireRed’s memory, this could point to a blank or garbage species.
To understand the phenomenon, one must first decode the name. In the early 2000s, the scene was flooded with "dumped" versions of Game Boy Advance games. Some were clean rips; others were corrupted or modified. A specific release group, or perhaps an individual using the alias "Squirrels," released a pristine version of Pokémon FireRed.
While the official title on the box was Pokémon FireRed Version, this specific ROM file was tagged with the internal game code "BPRE" and a specific ROM ID that translates to the integer 1636 in certain database circles. The filename often ended with "...Squirrels."
This specific file became the industry standard. It wasn't just a copy of the game; it was the copy. It was stable, uncorrupted, and free of the header issues that plagued other rips.
