How Video Game Cheats Are Made: Technical Overview of Reverse Engineering & Memory Manipulation

Cheat Creation Methods

Cheats exploit the gap between game logic and player agency. Common techniques:

1. Reverse Engineering

• Disassembly: IDA Pro, Ghidra convert machine code → assembly.
• Decompilation: Hex-Rays, Ghidra pseudo-C for higher-level logic.
• Dynamic Analysis: Debuggers (x64dbg, Cheat Engine) trace execution, find health/ammo addresses.

2. Memory Manipulation

• Value Scanning: Search for known values (health=100), narrow after changes.
• Pointer Chains: Static base address → offsets → dynamic value (multi-level pointers).
• Code Injection: Overwrite instructions (e.g., dec [health] → nop).

3. Logic Exploitation

• Glitches: Sequence breaks, collision exploits, integer overflows.
• State Manipulation: Save-file editing, network packet spoofing (multiplayer).

4. Tooling

• Trainers: Pre-packaged memory patches (Cheat Engine tables, WeMod).
• Bots: Automated input (aimbots, farm scripts).
• Mod Menus: Injected DLLs hooking rendering/input (GTA V, CoD).

Ethical & Legal Warning

• Single-player: generally tolerated (modding communities).
• Multiplayer: bans, legal action (CFAA, DMCA), ruins others' experience.
• Anti-cheat (BattlEye, EAC, Vanguard) detects most public methods.

Understanding internals is valuable for security research and game development—use responsibly.
