- Monospace font for perfect alignment
- Horizontal and vertical scrollbars

### 2. Byte Analysis
#### Normal Order
- HEX: Hexadecimal representation of selected bytes
- DEC: Corresponding decimal value
- !HEX: Bitwise complement in hexadecimal
- !DEC: Bitwise complement in decimal

#### Reverse Order
- HEX: Hexadecimal representation of bytes in reverse order
- DEC: Decimal value of reverse order
- !HEX: Bitwise complement in hexadecimal
- !DEC: Bitwise complement in decimal

### 3. Flexible Selection
- Direct selection of hexadecimal values
- Full line selection including offset and ASCII
- Automatic analysis update on selection

### 4. ASCII Pattern Analysis
- Comprehensive file-wide ASCII text scanning
- Detects various patterns:
  * Phone numbers
  * Short letter sequences
  * Alphanumeric codes
  * Potential 3-letter abbreviations
- Interactive results popup
- Supports multiple pattern types

### 5. Advanced ASCII Pattern Recognition
- Comprehensive file-wide text scanning
- Multiple pattern detection:
  * Possible Software Numbers (10-11 digits)
  * Vehicle Identification Numbers (VIN)
  * Potential Code Sequences
  * Possible PIN Codes
- Unique pattern occurrence counting
- Interactive results display
- Supports complex alphanumeric pattern matching

### 6. Pattern Analysis Features
- Detailed pattern identification:
  * Detects 3+ letter codes
  * Finds long numeric sequences
  * Highlights repeated patterns
- Occurrence frequency tracking
- User-friendly results popup
- Flexible pattern recognition

## Installation

1. Requirements:
   - Python 3.7 or higher
   - Tkinter (usually included with Python)

2. Install dependencies:
```bash
pip install -r requirements.txt
```

## Usage

1. Run the program:
```bash
python main.py
```

2. Features:
   - Click "Select File" to choose a binary file
   - Select bytes in the hex viewer (using mouse or keyboard)
   - View automatic analysis in Normal Order and Reverse Order panels
   - Use scrollbars to navigate large files

## Examples

### Byte Analysis
If you select bytes "4E 31":
- Normal Order:
  * HEX: 4E31
  * DEC: 20017
  * !HEX: [complement]
  * !DEC: [decimal complement]

- Reverse Order:
  * HEX: 314E
  * DEC: 12622
  * !HEX: [complement]
  * !DEC: [decimal complement]
