Cemu is a Nintendo Wii U emulator for Windows, and the download goes to the official server at github.com; we do not host the file. Version 2.6 is 25.2 MB and costs nothing.
A Wii U emulator under the MPL-2.0 licence
Cemu does one job: it emulates the Nintendo Wii U. The project is written in C++, published by the Cemu developers on GitHub, and released under MPL-2.0. Its source code is public at github.com/cemu-project/Cemu.
What a session with Cemu 2.6 involves
Cemu has a title manager that can export saves, and version 2.6 fixes a crash when the export path contains unicode characters. Graphics run on Vulkan, and this release reduces the number of sampler objects created, which helps drivers with low limits. A PPC debugger is also included, now with a right-click menu in the disassembly view.
Cemu against PPSSPP, RetroArch and PCSX2
The listed alternatives, such as PPSSPP, DuckStation and PCSX2, each target other hardware. RetroArch and BizHawk cover several systems. Cemu stays focused on Wii U, so it fits only if that console is what you want.
What's new in 2.6
Version 2.6 uses libusb as the HID/USB backend on Windows and fixes a regression in DS Virtual Console titles. The --force-interpreter option now always uses single-threaded CPU emulation.
