Cemu - Wii U Emulator 2.4

Cemu 是一款專注於在 Windows 上執行 Wii U 遊戲的模擬器，從 2015 年推出至今持續演進，已成為同類工具中的主流首選。它解決了 Wii U 主機已停產、玩家難以回味獨佔遊戲的痛點，最鮮明的特色是能將原本 720p 的畫面提升到高解析度輸出，並支援紋理強化、反鋸齒等畫質增強，同時透過多執行緒最佳化讓遊戲跑得更順暢，也保留了 mod 修改的彈性。開發團隊長期維護，更新雖不頻繁但穩定，整體評價普遍不錯。

這套軟體適合想在高畫質下重溫《薩爾達傳說：曠野之息》等 Wii U 獨佔作品的玩家，或是不想為了少數遊戲添購主機的 PC 使用者。與同分類的 Android 模擬器（如 SmartGaGa、BlueStacks）相比，Cemu 是唯一專注 Wii U 平台的選擇，沒有直接替代品，取捨在於它僅支援 Windows 且介面為英文，對不熟悉模擬器設定的新手稍有門檻。軟體本身免費，但使用前需留意自備遊戲檔案的合法性，以及電腦硬體是否足以應付高解析度渲染的需求。

Not all games are fully compatible, but the majority of popular titles run smoothly with proper configuration.

Does Cemu support online multiplayer?
Some online features work through CemuHook, but official Nintendo services are mostly unavailable.

What hardware is needed for Cemu?
A high-performance CPU (preferably Intel or AMD Ryzen) and a dedicated GPU (NVIDIA or AMD) are recommended for smooth gameplay.

Yes, but for the best experience, using a controller is advised.

Will Cemu support platforms other than Windows?
Multi-platform support is planned, but development priorities come first. Work on ports will begin after other core improvements.
