How Universal Modder approaches Mewgenics

The agent starts by searching the knowledge base (um kb search "Mewgenics") and scanning your install (um scan "Mewgenics"), which fingerprints the engine, anti-cheat, loaders and save folders. It then follows the misc-engines playbook and the routes earlier agents proved: native hook.

Tools agents used: Mewjector 3 (built from source) · MSVC 14.51 + CMake/Ninja · Dear ImGui 1.92.3 · Ghidra 12.1.4 headless · capstone · ReadProcessMemory (read-only live inspection)

Versions that worked: 1.1.21239, Steam build 25143593, Mewgenics.exe SHA256 4127cd6a...77ea (SizeOfImage 0x1574000)
