From ea69cac5266190cb7d0b45849809b5f692fe824d Mon Sep 17 00:00:00 2001 From: Kelsi Date: Thu, 12 Feb 2026 03:01:36 -0800 Subject: [PATCH] Add cross-platform x86 emulation via Unicorn Engine MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Solves Linux execution limitation without Wine! New Component: WardenEmulator - Uses Unicorn Engine to emulate x86 CPU on any platform - Can execute Windows Warden modules on Linux/macOS/ARM - Provides sandboxed execution environment - Intercepts Windows API calls with custom implementations Features: - CPU: x86 32-bit emulation via Unicorn - Memory: Emulated address space (1MB stack, 16MB heap) - API Hooks: VirtualAlloc, GetTickCount, ReadProcessMemory, etc. - Safety: Module runs in isolated emulated environment - Cross-platform: Works on Linux/macOS/Windows/ARM hosts Architecture: - Module code loaded into emulated memory at 0x400000 - Stack at 0x100000 (1MB) - Heap at 0x200000 (16MB) - API stubs at 0x70000000 (high memory) - Intercept and provide Windows API implementations Benefits vs Wine: ✓ Lightweight (no full Windows compatibility layer) ✓ Sandboxed (module can't harm host system) ✓ Cross-architecture (works on ARM, RISC-V, etc.) ✓ Full control over execution (can inspect/modify state) ✓ Easier debugging and analysis Build: - Added libunicorn-dev dependency - Conditional compilation (HAVE_UNICORN) - Falls back gracefully if Unicorn not available Status: Infrastructure complete, ready for integration Next: Connect WardenEmulator to WardenModule for real execution Note: RSA modulus extraction script added but needs refinement (current candidates are x86 code, not data section) --- CMakeLists.txt | 20 ++ extract_warden_rsa.py | 94 ++++++++ include/game/warden_emulator.hpp | 162 +++++++++++++ src/game/warden_emulator.cpp | 381 +++++++++++++++++++++++++++++++ 4 files changed, 657 insertions(+) create mode 100755 extract_warden_rsa.py create mode 100644 include/game/warden_emulator.hpp create mode 100644 src/game/warden_emulator.cpp diff --git a/CMakeLists.txt b/CMakeLists.txt index 9f87b12e..a4ec9ec8 100644 --- a/CMakeLists.txt +++ b/CMakeLists.txt @@ -25,6 +25,18 @@ find_package(ZLIB REQUIRED) find_package(PkgConfig REQUIRED) pkg_check_modules(FFMPEG REQUIRED libavformat libavcodec libswscale libavutil) +# Unicorn Engine (x86 emulator for cross-platform Warden module execution) +find_library(UNICORN_LIBRARY NAMES unicorn) +find_path(UNICORN_INCLUDE_DIR unicorn/unicorn.h) +if(NOT UNICORN_LIBRARY OR NOT UNICORN_INCLUDE_DIR) + message(WARNING "Unicorn Engine not found.
