Reverse engineering, analysis, and partial disabling of Steam's CEG (Custom Executable Generation) anti-tamper protections in t6sp.exe (Call of Duty: Black Ops II singleplayer), while preserving all anti-piracy mechanisms.
⚠️ Disclaimer: This analysis is for educational and research purposes only. It does not and will never facilitate piracy or unauthorized distribution of software. The focus is strictly on bypassing tamper protections to allow for legitimate reverse engineering, modding, and debugging workflows.
This repository documents the process of identifying, analyzing, and partially neutralizing CEG’s anti-tamper functionality in t6sp.exe. The intent is to allow deeper understanding and modification of the binary for personal or research use, without impacting the core anti-piracy measures enforced by Steam.
For the full technical write-up, including debugger techniques, CRC bypass strategies, and notes on function structure and behavior:
- Focuses exclusively on
t6sp.exe(Black Ops II SP). - Preserves all anti-piracy checks.
- Does not contain or link to any copyrighted game files.
- Designed for experienced reverse engineers and hobbyists interested in software protection mechanisms.
