Roblox Random PCG CLI Tool

A lightweight C++ command-line utility designed to generate, and reverse-engineer (crack) the PCG-based pseudorandom number generator (PRNG) used in Roblox (Random.new()).

Features

• Crack Mode: Reverse-engineer and find the initial 64-bit seed using a sequence of generated numbers from a file.
• Single Mode: Find a valid seed using just a single target value within a specific range.
• Generation Mode: Generate reproducible random integers, floating-point numbers, and unit vectors identical to Roblox's native Random object behavior.
