Convert a file to FIRM

About FIRM files

A .FIRM file is a raw binary executable format, most famously serving as the bootloader payload for modded Nintendo 3DS consoles using Luma3DS. Unlike standard software containers, these files run on "bare metal" hardware, specifically coordinating the ARM9 and ARM11 processors during the boot sequence. This is a common issue for standard users: the format is proprietary, undocumented by official channels, and cannot be opened or viewed in standard text editors like Microsoft VS Code without seeing garbled binary data. A secondary, less common use case involves firmware update packages for Evolis ID card printers. Because these files are hardware-specific instructions rather than data containers, you generally cannot "convert" them into consumer formats like PDF or JPG without rendering them useless. For developers and reverse engineers analyzing the code, the viable conversion path is transforming the .FIRM payload into an ELF (Executable and Linkable Format) or separating the binary sections for analysis in tools like IDA Pro or Ghidra. For standard users, the "conversion" is simply renaming or placing the file correctly - typically ensuring the primary payload is named boot.firm on the root of an SD card.

Convert.Guru analyzes your FIRM file, detects the exact format, and lets you read the text inside.

Users also converted A64, 3DSX and SWI files.

The FIRM Converter Story

The history of Convert.Guru began over 25 years ago in California with Tom Simondi’s file-format database. A former contributor to Space Shuttle development and a software pioneer of the 1980s, Simondi established a trusted resource for file type analysis that was even referenced by Microsoft Windows XP. Today, we use modern technology to process and convert thousands of file formats while continually improving our FIRM converter.
