Three lightweight binary compare utilities for fast firmware/ROM diffing
This pack brings together three classic Windows tools for side-by-side binary comparison. Ideal for firmware BINs, ROM dumps, ECU files and any raw data where offset-level differences matter.



What’s included

• Fairdell HexCmp2 (v2.34) — classic hex editor/compare with a full toolbar UI and synchronized views (About dialog shows Ver. 2.34, 24-Jan-2008).
• Compare Files by The Wizard (v1.00) — ultra-minimal two-pane hex viewer with LEFT/RIGHT loaders and live address indicator.
• Big_Bin_File_Compare [Kody ©2004] — simple dual-pane comparer focused on quick visual checks of large BINs.
  

At a glance — key differences

• HexCmp2: most feature-rich; comfortable editor-style UI for longer sessions and careful inspection.
• Compare Files (The Wizard): single-purpose, fast to open; great for quick byte checks at a given address.
• Big Bin File Compare: similarly lightweight with dual panes and position readout; handy for quick side-by-side scans.

Typical uses

• Validate firmware edits or patches before flashing.
• Compare calibration BINs and confirm expected offsets changed.
• Investigate regressions or data corruption between versions.
