Modern Warfare 2 Android — Release v0.0.2 (Snapdragon & Vulkan 1.0 Update)

Version 0.0.2 brings comprehensive fixes for Qualcomm Snapdragon (Adreno) chips, lowers the hardware compatibility floor to Vulkan 1.0, introduces ARM64 Prime-core CPU thread affinity, implements TBDR mobile tile-rendering optimizations, and adds an offline mod directory overlay (mods/).

🎮 What's New in v0.0.2

⚡ Qualcomm Snapdragon (Adreno) Fixes

  • Black Terrain, Skybox & Flicker Resolution:
    • Automatically identifies Adreno GPUs (vendorID == 0x5143) and routes BC compressed textures through software SIMD decoding to prevent Adreno's 1-bit alpha sampling hardware bug.
    • Representation-safe texture uploads and restaging: guarantees format consistency and validates payload byte size against image metadata, fixing black screens, flickering foliage, and missing geometry.
    • Option MW2_FORCE_BC_HW=1 provided for users running custom clean Mesa Turnip drivers.
  • Snapdragon Prime-Core Thread Affinity:
    • Automatically detects ARM big.LITTLE / tri-cluster architectures (Snapdragon 865 through 8 Gen 3).
    • Pinned main game loop to the Prime Core (Cortex-X1/X2/X3/X4), recorder/dispatch thread to Performance Cores, and background tasks to Efficiency Cores via Bionic sched_setaffinity.

📱 Vulkan 1.0 Mobile Support

  • Lowered Manifest Feature Requirement:
    • Decreased android.hardware.vulkan.version requirement from 0x401000 (1.1) to 0x400000 (1.0).
    • Clean feature decoupling: dynamic rendering and extended dynamic state are dynamically negotiated, with automatic fallback to classic Vulkan 1.0 render passes and negative-viewport maintenance extensions.
  • TBDR Mobile RenderPass Optimization:
    • Configured VK_ATTACHMENT_STORE_OP_DONT_CARE on stencil and temporary depth attachments to prevent GPU tile-memory thrashing on mobile SoCs.

🧩 VFS Mod Directory Overlay

  • Offline Bots & Loose Asset Support:
    • Transparent virtual filesystem overlay via MW2_MOD_DIR or <GameRoot>/mods/.
    • Enables loading offline Bot Warfare GSC mods, custom scripts, localized language files, and loose assets without repacking .ff FastFiles.

🛡️ Hardened Tooling & Asset Ingestion

  • XDVDFS Disc Extractor (tools/xdvdfs.py):
    • Added strict sector bounds validation against total image size.
    • Prevented infinite recursion and directory loops.
    • Sanitized filenames against path traversal (.., slashes) and enforced destination containment.
    • Added truncated read detection.
  • Asset Fetching (tools/fetch_asset.py):
    • Fixed order-of-operations bug where files were unlinked prior to reading header bytes.
    • Added zip-bomb resource limits (capped total unpacked bytes to 15 GiB and maximum entry count to 50,000).

🔄 Upstream Engine Synchronization

  • Merged upstream FOV slider support and frame arena write-combining optimization.
  • Added network and security notices for LAN / matchmaking.

📦 Requirements

  • OS: Android 8.0 (Oreo) or higher (API 26+)
  • Architecture: arm64-v8a (64-bit ARM)
  • GPU: Vulkan 1.0 or higher (Snapdragon / Adreno 600+, Dimensity / Mali-G57+, Exynos / Xclipse, Tensor)
  • RAM: Minimum 4 GB, Recommended 6 GB+
  • Storage: ~7 GB free internal storage for game data
  • Game Files: An unmodified Xbox 360 Modern Warfare 2 disc image (.iso)
