🆕 What’s New (July 2025)

Major Improvements in This Release

• Multi-Region VBF Support
  Converts all firmware/data regions from Ford .vbf files (not just the first). Output HEX is always 100% complete, even for complex VBFs.

• Live Metadata Display

  • Auto-parses and displays VBF info: Version, part number, description, region table, and more, before conversion.
  • Highlight: See start/end addresses and size of all data regions in the file.

• Modern, Professional UI

  • Dark Theme (High-DPI and Retina-ready)
  • Drag & Drop Support: Drop any .vbf onto the window to instantly load it.
  • Red Exit Button for quick closing.
  • Copyable/Selectable fields for power users.

• Sound Effects

  • Success and Error chimes after conversion (loads wav.wav and wav-4.wav from the /Sounds/ folder if present, otherwise uses system beep).
  • Sounds stop cleanly if you close the window during playback.

• File Path and Extension Fixes

  • Output is always .hex by default (drag/drop, file browse, or manual typing).
  • No file paths or headers are ever added to your HEX output—only valid Intel HEX records.
  • Handles both relative and absolute paths and checks for file existence.

• Better Input Validation & Error Handling

  • Input validation for file existence, type, and output name before running.
  • Improved error messages in the GUI and via popups.
  • Handles corrupt or incomplete VBFs gracefully.

• Robust Cross-Platform Sound Handling

  • Loads sound files using safe resource paths for Windows, Mac, and Linux.

• Ready for Power Users

  • All UI fields are selectable and copyable.
  • Output field is forced to .hex (unless you override).
  • Drag-and-drop, file browse, or type paths directly.
  • EXE is Windows only, Python script runs everywhere.

What is a VBF File?

A .VBF (Vehicle Binary File) is Ford's standard format for ECU/PCM firmware updates, containing data blocks, metadata, and sometimes custom scripts.
This tool extracts the raw firmware section and converts it to a common HEX/BIN file for use with programmers, bootloaders, or analysis tools.

Usage

1. Select Input: Click Browse Input VBF and pick a Ford .vbf file.
2. Select Output: Choose where to save the resulting .hex file (or rename extension to .bin for pure binary).
3. Convert: Click Convert VBF to HEX.
4. Done! You'll see a success message and can now use your HEX/BIN file with other tools.

FAQ

Q: Does this tool work on Mac or Linux?
A: The Python source runs anywhere with PyQt5 and Python 3.10+. The EXE is Windows only.

Q: Can I convert files in batch?
