RTTI Image Extractor

This Python script automatically extracts the largest possible image from .rtti binary files. It reads potential image dimensions, tries to extract corresponding image data, and saves the largest image it can find as a PNG file.

How It Works

The script scans the binary contents of all .rtti files for potential image dimension data. It attempts to read the image data based on these dimensions and, if successful, saves the largest valid image as a PNG file.
