Modern Warfare 2 Android — Release v0.0.1 (Alpha)

Initial release of the native Modern Warfare 2 (2009) recompilation port for Android ARM64 devices (com.mw2.recomp.sp).

This project statically recompiles the original Xbox 360 PowerPC executable (default.xex) into native 64-bit ARM machine code (libmw2.so), featuring an integrated Android launcher, XDVDFS disc installer, Vulkan rendering backend, and low-latency AAudio subsystem.

🎮 What's Included in v0.0.1

🚀 Core Engine & Native Runtime

  • Native ARM64 Execution: Powered by XenonRecomp static PowerPC recompiler, running without CPU emulation overhead.
  • Vulkan Renderer Backend:
    • Full Vulkan 1.1 legacy fallback path for widespread mobile SoC compatibility (Adreno & Mali).
    • High-performance shader translator converting Xenos microcode to SPIR-V.
    • Dedicated application-level shader cache with start-up prewarming to eliminate in-game shader compilation stutter.
  • Audio Subsystem:
    • Low-latency AAudio native sink at 48 kHz stereo with linear sample interpolation.
    • Smooth APU mixer scheduling with burst-free catch-up logic and zero real-time heap allocations.
  • Input & Controls:
    • Virtual on-screen touch overlay with multi-touch support.
    • Full physical gamepad support (Bluetooth / USB-C controllers: Xbox, DualShock/DualSense, generic HID).

🛡️ Stability & Security Hardening (Deep Audit Fixes)

This release incorporates all fixes from our comprehensive security and stability source audit:

  • GPU Pipeline Stability (Mali-G68 / Dimensity & Exynos):
    • Bypassed persistent VkPipelineCache on Arm Mali GPUs to eliminate documented driver cache deadlocks during monolithic pipeline compilation.
    • Injected static dummy viewports and scissors to prevent mobile driver null-pointer dereferences under dynamic state configurations.
    • Configured null pColorBlendState on depth-only subpasses (colourFormat == VK_FORMAT_UNDEFINED) complying with Vulkan specifications.
    • Restored depthControl and modeCntl in legacy Vulkan 1.1 shader cache prewarming keys.
    • Synchronized all VkPipelineCache accesses across draw pipeline compilation, library linking, and cache saving.
  • Storage & Path Traversal Prevention:
    • Sanitized custom GPU driver imports in DriverStore.kt, strictly rejecting dot-segment traversal (. and ..) and enforcing canonical storage containment.
    • Staged driver replacement transactionally to eliminate risks of app data loss.
  • Hardened XDVDFS Disc Extraction:
    • Guaranteed imageSize_ initialization prior to partition probing in launcher/disc.cpp, supporting all standard and non-zero partition disc layouts.
    • Bounded allocation constraints on directory metadata (32 MB cap) and verified entry boundaries against image bounds.
    • Sanitized extracted filenames against path traversal components (/, \, ..).
    • Added 3-point sample chunk integrity validation (header, middle, and tail) before skipping existing matching-size assets.
  • Installer Safety:
    • Aborts extraction immediately if target device storage is insufficient.
    • Verifies exact stream copy byte counts to prevent corrupted or truncated source files.

📦 Requirements

  • OS: Android 8.0 (Oreo) or higher (API 26+)
  • Architecture: arm64-v8a (64-bit ARM)
  • GPU: Vulkan 1.1 compatible (Adreno 600+, Mali-G57/G68/G77/G78+, Immortalis)
  • 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)

📥 Installation Guide

  1. Download and install app-campaign-release.apk from the Assets below.
  2. Transfer your legal Modern Warfare 2 Xbox 360 disc image (.iso) to your Android device (e.g. Downloads folder).
  3. Open the MW2 launcher on your phone.
  4. Tap Select ISO / Install Game, choose your .iso file, and wait for the extraction to finish.
  5. Tap Launch Campaign and enjoy!
