What's New

Checksum Finder

Profile-based checksum verification with guided workflows. Designed for validated algorithms and safe defaults.

Checksum Map Runner

Run multiple checksum rules across a dump and generate a clear report after edits.

Safe Read‑Only Scripts

Helpers for verified layouts (e.g., VIN decode / redundancy checks) without modifying your data.

UI Reliability

Improved scrolling and panel sizing for long files, ensuring a stable and predictable workflow.

Tip: Open the Documentation to learn every button, right‑click action, inspector field, and checksum workflow.

Visual Tour

Preview the workspace, inspector, and script tools. Click any image to enlarge.

Core Features

Hex + ASCII View

Address, hex, and ASCII columns in one fast canvas view.

Keyboard Editing

Edit nibbles in hex mode or type ASCII directly.

Selection Tools

Mouse drag selection with live inspection and quick actions.

Tabs + Compare

Open multiple buffers, compare tabs, highlight differences.

Markers & Colors

Mark bytes with color tags, apply to master buffer if needed.

Autosave

Protects work with periodic background saves.

Context Actions

Right-click for XOR, fill, swap bytes, and selection tools.

Clipboard Ready

Copy selections or whole buffers, paste hex or text.

Checksum Finder

Profile-based checksum checks to validate data blocks after edits.

Script Runner

Run built-in scripts for calculations, reports, and safe read-only analysis.

Calculations Included

Selection Sum8 (8-bit sum)
Selection XOR8 (8-bit XOR checksum)
Selection Sum16 (16-bit sum)
XOR with value (apply hex XOR to selection)
Fill with value (overwrite selection with hex value)
Inspector checksums: SUM, XOR, SUM16
Expression evaluator with variables: hex, dec, hex_inv, rhex, sel[]
Checksum Finder profiles (validated algorithms, endian-aware display)
Checksum Map Runner (run multiple checksum rules and export a report)
Read‑only analyzers (VIN / redundancy checks when supported)

How to Use

  1. Open a binary file and review bytes in the hex/ASCII view.
  2. Select bytes with your mouse and inspect values instantly.
  3. Edit in hex mode or ASCII mode as needed.
  4. Use the Scripts panel for checksums, XOR, fill operations, and read-only analyzers.
  5. After edits, run Checksum Finder / Checksum Map Runner to validate supported blocks.
  6. Open Documentation for a full guide to menus, inspector fields, and right-click tools.
  7. Compare tabs to highlight changes across dumps.
  8. Save the updated buffer to disk when finished.

Capabilities

Binary Analysis

Inspect raw EEPROM and firmware bytes with precision.

Fast Edits

Immediate updates with autosave support and clear history.

Data Transformation

Swap, XOR, and fill ranges for quick patch workflows.

Validation

Use checksum tools and expressions to verify changes.

Workflow Safety

Compare buffers side-by-side and highlight differences.

Multi-Tab Projects

Keep multiple dumps open and switch instantly.
