## What it is
Cemu is an open-source Wii U emulator written in C++ that runs most Wii U games and homebrew in a playable state on PC. It is actively developed and available for 64-bit Windows, Linux, and (experimentally) macOS.

## Use cases
- play wii u games on pc
- emulate nintendo wii u console
- run wii u homebrew on desktop
- play wii u games on linux
- enhance wii u game graphics with packs
- use wii u gamepad and motion controls on pc

## When to choose
- you want to play Wii U games on Windows, Linux, or macOS with high compatibility
- you want active development, frequent releases, and community graphic packs
- you need controller, motion, and GamePad screen emulation

## When to avoid
- you need to emulate other consoles like Switch or Wii - use dedicated emulators
- you need a stable macOS experience - the native macOS build is experimental with degraded performance
- you lack a reasonably powerful GPU and CPU - emulation demands modern hardware

## Facets
- artifact type: application
- maturity: active
- function: simulation, graphics, gui
- domain: gaming-tools, cross-platform, developer-tools
- platform: windows, cpp
