Mrowr Purr's Reverse Engineering Journey

As I learn to reverse engineer video games, I am putting the source code for everything that I learn here.

Learning Goals

I one day hope to have a variety of examples demonstrating:

• Some examples of simple x86 and x64 assembly programs
• Program memory read/write via external executables
• Program memory read/write via internally injected libraries
  • Libraries / Tools for .dll injection (using different patterns)
• Detours / Trampolines
• Cheat Engine cheat tables for various games
• Minimal modding frameworks for various games in various languages
  • C++
  • Rust
• Embedded virtual machines with library with bindings to host process memory alteration (with REPL)
  • Lua
  • JavaScript
  • Python
• And more!

I'm just getting started learning, so we'll see!

Learning Resources

These are not official recommendations, I have not watched all of them!
