Revamp Old DLL Client

Job ID: 40311982

Budget: $250 – $750 USD

Patch Old Dll Client to Act like new Dll client

The client is fully disassembled and running under Ghidra/IDA Pro; what it no longer does is pass the latest server-side authentication. I need you to step in, locate every point where the new build now fails—hash verification, version matching, encryption routines, or any combination of them—and patch those spots so the executable sails straight through the handshake.

The login request packet is known to be touchy, so give that message extra scrutiny. Beyond that, assume the protocol may have shifted; part of the assignment is to detect and adapt to whatever the server now expects.

Deliverables
• A working patched binary, or a loader/patcher, with concise usage instructions
• A brief technical note describing the modified functions, offsets, or constants and the rationale behind each change
• Visual proof (screenshot or short clip) showing the client authenticating and entering the game world

Please mention one or two past binaries you have successfully revived or re-aligned so I can gauge fit. Once I receive your build I will test it against the live server immediately
