: Secure the 1636 Fire Red (Squirrels) .gba file.

"1636" is a user-generated tag from a foreign ROM site (possibly Korean or Brazilian Portuguese, where the ROM hacking scene is massive). Often, these sites number their uploads sequentially. "1636" was simply the file ID for a specific upload of Pokémon Fire Red that has since been modified with a sprite patch.

However, the legacy of "Squirrels" is not without its complications. The ubiquity of this specific ROM created a fragmentation between legitimate preservation and casual emulation. For years, the Pokémon community operated almost exclusively on this pirated base. When Nintendo finally released FireRed on the Virtual Console or through modern collections, players found that their old saves and hacks were incompatible with the official, slightly different files. This highlights a unique challenge in game history: the "definitive" version of the game for millions of people was not the version sold in stores, but the version shared on the internet.
