: To ensure you have the correct file for patching, verify that your ROM's CRC32 hex code is DD88761C How to Install & Patch
Ignore the "squirrels" error. Focus on the identifier. Use a trustworthy emulator like mGBA and only source the ROM if you own the original cartridge. For casual play without legal concerns, any clean US ROM of Pokémon Fire Red will work perfectly—you do not strictly need dump 1635 .
To play a ROM hack, you generally cannot just download a finished game file due to piracy laws. Instead, you "patch" your clean Squirrels ROM with a hack file. 1. Requirements
Use an online tool like the Marc Robledo ROM Patcher or a standalone program like NUPS. Upload your Squirrels .gba as the "ROM file" and your hack file as the "Patch file". Run on an Emulator: PC: mGBA is the top recommendation for accuracy. Android: MyBoy! is highly preferred for mobile. iOS: Delta is the standard modern choice. Why "Squirrels"?
