The convergence of mobile and desktop computing has driven demand for running legacy x86-64 applications on ARM-based Android devices. This paper examines the architectural challenges and solutions for implementing a 64-bit Windows emulator on Android. We analyze the requirements for CPU emulation (x86-64 to ARM64), system call translation (Windows NT kernel to Android Linux kernel), and GPU acceleration. Existing solutions like Winlator, ExaGear, and Box86/Box64 are evaluated. Results indicate that while full system emulation is possible, performance is limited by memory addressing, 64-bit exception handling, and binary translation overhead. A hybrid approach using Wine (Windows compatibility layer) combined with a user-mode x86-64 emulator yields the most practical balance between compatibility and speed.
For users comfortable with the command line, the Termux terminal emulator combined with proot-distro and Wine for ARM64 can run 64-bit Windows apps. 64 bit windows emulator for android
