DLL Patch for Game Login

I have a Windows game whose authentication routine lives inside a single DLL. The goal is simple: locate the check that blocks the first network handshake and neutralise it so the login packet goes out unhindered. You will be reversing without source, working directly in disassemblers such as IDA Pro or Ghidra, and producing a drop-in replacement library that keeps every exported symbol intact while bypassing authentication.

All materials you’ll receive:
• the original x86-64 DLL
• packet captures showing the expected login flow
• a minimal loader for quick testing

Deliverables
• Patched DLL that loads in the live game and sends the login packet successfully
• Brief change log listing touched offsets and rationale
• Your IDA/Ghidra project files for future reference

Acceptance criteria: on my Windows-10 test machine the game must start, transmit the login packet (confirmed in Wireshark), reach the lobby screen, and remain stable for at least five minutes.

Please reach out only if you’re comfortable reading raw assembly, navigating complex control flow, and crafting byte-level patches for game software.

dont waste my time if you dont have reverse engineer knowledge, deep assembly knowledge and expertise with tools like ida and ghidra !!
