Title: 1636 Pokémon Fire Red USquirrels – A True Story of Glitches, Grinding, and Rodent Mayhem

Posted by: RetroRival | Date: April 12, 2026

Let me tell you about the worst, best, and most unhinged Pokémon run I’ve ever endured.

It started as a joke. A dare, really. My friend said, “You can’t beat Fire Red using only squirrels.”

I said, “There are no squirrels in Kanto.”

He said, “Then you’re already screwed.”

But the internet had other ideas. A few clicks later, I stumbled onto a shady ROM hack forum. Buried in a thread from 2012, under a folder labeled “USQUIRRELS,” was a single .ips patch. The description read: “Fire Red but every wild Pokémon is a squirrel. Also the numbers are wrong. Good luck.”

No readme. No credits. Just chaos.

The 1636 Mystery

I patched my Fire Red ROM, booted it up, and immediately knew something was off.

The title screen still said “POKEMON FIRE RED,” but the subtitle flickered to “USQUIRRELS EDITION” for a split second. Professor Oak’s intro played normally—until he said, “This world is inhabited by creatures called... squirrels.”

My starter choices?

I picked the fire squirrel, named him Cinderfluff, and stepped onto Route 1.

Every. Single. Encounter. was a Pidgey. But the Pokédex called them “Oaksquirrels.” Their cry was a sped-up chipmunk noise. Their type? Normal/Flying but with a hidden ability called “Nut Stash” (restores 1/16 HP each turn if holding a Berry). 1636 pokemon fire red usquirrels

Then I noticed the number: 1636.

My Pokédex said “Seen: 1636. Owned: 1.” I had only fought two Oaksquirrels. I checked the start menu. The play clock? 00:00. The trainer ID? 1636. Every time I caught a squirrel, the “Owned” counter jumped by random amounts—sometimes +1, sometimes +47.

I wasn’t playing Pokémon anymore. I was feeding a glitch.

The Grind to Indigo Plateau

You think a normal Nuzlocke is hard? Try a “Squirrel-only” run where the level curve doesn’t exist.

By the time I reached Viridian Forest, I had 1636 encounters logged. My party? Six squirrels:

The game broke further at Lavender Town. The music slowed down. The ghosts were squirrels wearing bedsheets. Mr. Fuji gave me a “Squirrel Flute” that did nothing but play a 10-second loop of “We Will Rock You” on a kazoo.

And still, the number 1636 appeared everywhere. Gym leader teams? All 1636 CP. Poké Ball prices? 1636. Even the bike cost 1636,000, which I couldn’t afford because squirrels don’t hold money.

The Elite Four – Final Madness

The champion wasn’t Blue. It was a giant squirrel named U.S. Quirrel (yes, with two R’s). Its team:

I lost 47 times. On attempt 48, my game glitched so hard that my Cinderfluff learned “Splash but it actually does 1636 damage.”

I won. The Hall of Fame screen showed 1636:00 playtime, 1636 Pokémon caught, and my name as “U Squirrel.”

The Takeaway

Would I recommend the 1636 Pokémon Fire Red USquirrels ROM hack? Absolutely not. It corrupted my save file, gave me tinnitus from the kazoo flute, and I’m pretty sure it installed a crypto miner.

But for one insane week, I lived the dream of being a squirrel master. And isn’t that what Pokémon is really about? Friendship, determination, and an unreasonable number of rodents?

Now if you’ll excuse me, I need to go apologize to my actual backyard squirrels. They’ve been staring at my window for three days.

P.S. If anyone knows what “1636” actually references, please tell me. I’ve lost sleep. My best guess is the year Harvard was founded, which means... Ivy League squirrels? I hate it here.

1636 - Pokemon Fire Red (U)(Squirrels) " is not a unique ROM hack itself, but rather the industry-standard "clean" base ROM used for creating and applying patches for popular Pokémon ROM hacks. It is a 1:1 digital dump of the original v1.0 Pokémon FireRed cartridge, originally released for the Game Boy Advance. Why "Squirrels"?

The name refers to the scene group or individual who originally dumped the game from the cartridge to a digital file. In the ROM hacking community, it is considered the most stable version because:

Version 1.0: Unlike the later v1.1 release, v1.0 is the most widely documented by hackers, making its memory addresses predictable for mods.

Patch Compatibility: Almost every major modern hack—such as Pokémon Unbound, Radical Red, and Rocket Edition—requires this specific "Squirrels" base to ensure the patch works without crashing the game. Core Technical Features

Because this is a clean copy of the original 2004 game, it contains only the standard features of the retail release unless you apply a patch:

Title: The Digital Relic: A Comprehensive Analysis of the "1636 - Pokemon Fire Red (USquirrels)" ROM and Its Impact on Software Preservation and Culture

Abstract

This paper explores the significance of the ROM image identified as "1636 - Pokemon Fire Red (USquirrels)," a specific digital artifact of the 2004 Game Boy Advance title Pokémon FireRed. While seemingly just a file name to the casual observer, this specific ROM dump represents a cornerstone of the retro-gaming preservation movement and the emulation scene. By examining the technical specifics of the dump, the role of the release group "Squirrels," the implementation of the Mr. Perfect encryption crack, and the resulting explosion of the ROM hacking subculture, this analysis positions the USquirrels ROM not merely as a pirated game, but as the definitive "canonical" text for the modern Pokémon community.

1. Introduction

In the realm of digital preservation and video game culture, certain files transcend their utilitarian purpose to become historical artifacts. The file designated 1636 - Pokemon Fire Red (USquirrels).gba is one such artifact. It serves as the foundational substrate for the majority of English-language Pokémon ROM hacks produced in the last two decades. Yet, its ubiquity is matched only by the obscurity of its origins. Why is this specific version, dumped by a group named Squirrels, the industry standard? Why do modders and hackers insist on this specific 16-megabyte file? This paper argues that the USquirrels ROM is a case study in the intersection of software protection, community standardization, and the creation of a digital heritage standard.

The Experiment

The goal of Dr. Elara and her team was to see if these enhanced squirrels could not only survive but thrive in the world of Pokémon. They theorized that by integrating Pokémon DNA into the squirrels, they could adapt to the environment in extraordinary ways, potentially even allowing them to communicate or partner with Pokémon.

Their test subject, a particularly clever and agile squirrel named Nutmeg, had been infused with the essence of Charmander. The results were astonishing; Nutmeg could generate small flames from its body and possessed strength and agility beyond that of ordinary squirrels.

3. The "Squirrels" Dump and Technical Context

The provenance of the USquirrels ROM traces back to the warez and emulation scenes of the mid-2000s. "Squirrels" was a release group active during the GBA era, credited with dumping (extracting the data from the physical cartridge) numerous titles.

In the early 2000s, dumping a GMA game was not a trivial plug-and-play process. Nintendo employed various forms of copy protection to prevent piracy, and early ROM dumps often suffered from "intros" (added code to display the cracking group's logo) or missing data due to improper bit-reading.

The USquirrels release gained legendary status because it was a "clean" dump. Unlike other releases that might have been corrupted or altered, the Squirrels dump was a 1:1 binary copy of the game's mask ROM. This lack of modification was crucial for the emergence of the hacking scene, as any alteration to the file structure could render the game unstable or incompatible with patching tools.

Review of “1636 Pokémon Fire Red USquirrels”
Rating: ⭐⭐☆☆☆ (2/5)

This bizarre ROM hack replaces all wild Pokémon with various squirrel-like creatures (Pachirisu, Greedent, plus poorly sprited original ‘USquirrels’). The year “1636” seems to be a colonial theme — trainers wear pilgrim hats, and Poké Balls are replaced with acorn slings.

Pros:

Cons:

Verdict: Only for hardcore weird ROM hack collectors. Avoid unless you love squirrels and glitches.
