Usually, Cemu updates tend to be frequent, but for the last few months, there haven't been any new major build releases. Recently though, the Cemu update drought since February 2022 is over, with the release of the experimental version 1.27.0. There's been some tweaks and overall improvements, bringing support for .wua files, a new audio backend, and auto-detection for update and DLC files, meaning you no longer have to install them. Library scanning has also been revamped, taking much less time than before, for those with large Wii U game libraries.
In addition, the Cemu team provided an update on how the Linux port has been coming along. As of this month, the developers have managed to get Cemu booting fully on Linux, including on the Steam Deck. However, there's still a lot to continue working on, including getting sound working, networking features, and general UI fixes. According to the team, the Linux release should take another 1-3 months before it's ready for the public.
- 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
