## What it is
Hangover is a compatibility layer that runs x86_64 and x86_32 Windows applications on ARM64 (aarch64) Linux by combining Wine with emulator DLLs (FEX, Box64). It emulates only the application code while executing Wine/Unix system calls natively for better performance.

## Use cases
- run Windows x86_64 apps on ARM64 Linux
- run 32-bit Windows applications on aarch64 without 32-bit Unix libraries
- run x86 Windows games on ARM Linux laptops
- execute Windows software on ARM64 servers via Wine
- run ARM64 Windows apps natively without emulation
- run x86_64 Windows apps on RISC-V Linux

## When to choose
- you need to run x86/x86_64 Windows applications on ARM64 Linux with Wine
- you want better performance than emulating an entire Wine installation under Box64 or QEMU
- your system lacks 32-bit Unix libraries but you need to run 32-bit Windows apps
- you want to run native ARM64 Windows applications without any emulation

## When to avoid
- you need to run Windows applications on x86_64 Linux hosts (use plain Wine)
- you require PPC64le support, which is no longer maintained
- you need a turnkey GUI solution rather than a Wine-based compatibility layer
- your application depends on kernel drivers or deep system integration that Wine cannot provide

## Facets
- artifact type: application
- maturity: active
- function: interpreter, simulation
- domain: operating-systems, cross-platform, developer-tools
- platform: cli
- tags: wine, emulation, x86-emulation, arm64, windows-apps, fex, box64, wow64, linux
