Wii U Emulation: Cemu 1.27.0 Released
It’s been a few months since the last Cemu release, so the team behind the popular Wii U Emulator have decided to release a new update!
Cemu 1.27.0 brings significant performance improvements, such as a much faster title scan (which should be noticeable if you have a larger library). Cemu 1.27.0 also brings support for a new file format “Wii U Archive” (.wua), a container optimized for Cemu which supports multiple titles in a single file (to have for example a game and all its DLCs in a single file). And, as always, multile bug fixes, as well as under-the-hood changes.
This release is said to be “experimental”. Practically, Experimental here seems to mean it’s a beta, and as such it needs to be downloaded manually (link below).
What is Cemu
Cemu is a Wii U emulator that’s been around for quite some time allowing you to play the console’s titles on your PC. While the Wii U was a commercial flop, it is worth saying that many popular Switch titles are direct ports of its games with such titles including Mario Kart 8, Zelda: Breath of the Wild and New Super Mario Bros U. This presents the opportunity of emulating these titles on PC, often with graphics packs/mods that provide a much nicer experience, without the pretty high requirements of Switch emulators such as Ryujinx and Yuzu. Thanks to this, the emulator earned a good deal of popularity over the years as even a low-range gaming PC equipped with older cards like the GTX 960 suffices for Mario Kart 8 and many other titles.
Cemu 1.27.0 – What’s new
From the changelog:
- Reworked title management from the ground up
- Scanning for titles should be a lot faster. Very noticable if you have a large library
- Updates and DLC no longer need to be installed. Cemu can now detect and load them directly from the game path folders
- The title manager window no longer is restricted to showing only one entry per title id, making it easier to manage duplicates
- Introducing support for a new file format for games which we dubbed Wii U archive (.wua):
- Supports multiple titles in a single file (e.g. a game combined with it’s update and DLC)
- Cemu can play them directly and display them in the game list
- Uses compression, resulting in a smaller size than WUX or extracted folder format
- Lossless, can be converted back to the original files
- You can easily convert any of your games into .wua format via the Title Manager
- A standalone tool, including source code, for packing/unpacking is available here
- Added Cubeb audio backend (see our roadmap for details)
- Added a workaround for sampler rounding behavior differences between Wii U and OpenGL/Vulkan. This fixes invisible effects in some Wayforward games
- Opening the GamePad view will no longer blank out the main window on OpenGL
- Fixed Ctrl + Tab hotkey not toggling between TV and GamePad view
- General debugger improvements. Added breakpoints will now be remembered across sessions
- Reworked PDM (Play Diary Manager) service to be a bit more accurate. If you use a full mlc dump, Cemu will show the playtime stats from your console in the game list.
- Implemented nn_ac API GetAssignedAddress() and GetAssignedSubnet()
- Improved texture cache heuristics. Should save a bit of VRAM and avoid some unnecessary texture copies
- Reworked GX2R API and fixed some bugs in the process. Transformers Prime should no longer crash on boot
- Fixed an issue in the RPL loader where it would generate the wrong branch type. Fixes Your Shape: Fitness Evolved crashing on boot
- Fixed a crash that could occur when a game tried to access the GamePad camera
- Added a way to specify IP and port before selecting a DSU controller
- Tons of under the hood changes. Including:
- Almost fully migrated to CMake
- Upgraded from C++17 to C++20
- Reworked internal string handling to use UTF8 almost everywhere
- Reworked path handling to be more robust. Relative paths and network storage locations should work now.
- Reworked emulated system libraries: coreinit atomic, coreinit FS, nn_aoc
