A development build with focused fixes
DuckStation’s latest rolling development build, published September 12, 2026, is an experimental update to the PlayStation emulator for Windows, Linux, and macOS. The build is generated from ongoing development and may receive less testing than a stable release.
The most visible change is a fix for video prerotation when blur effects or transitions are active. This benefits vertically oriented games, since DuckStation supports rotating the display for vertical or TATE titles. The update also fixes a rare crash that could occur when video hardware initialization failed.
Debugger and achievements updates
The Qt desktop interface gains a threads view and call-stack view in the debugger. The stack view is linked to the memory view, while debugger breakpoints can now be saved to INI files, making debugging sessions easier to restore. These additions complement DuckStation’s integrated and remote debugging features.
Achievement notifications and lists receive corrected padding, and achievement popups now show a category badge. The build also adds the RetroAchievements game ID to the game properties screen.
Interface, settings, and media handling
Several smaller interface changes improve day-to-day organization. Game directories no longer receive an unwanted trailing slash, the disc-selection dialog receives additional styling, and the memory-card editor combines its import buttons. The track summary list receives a small presentation change, while dropdowns use an expand icon.
The game list can now identify Audio CDs, and game properties are disabled for PSF files and Audio CDs where those controls do not apply. DuckStation also avoids carrying non-sensitive user preferences into game-specific settings, prevents unchanged list settings from being marked dirty, and disables post-processing when settings are reset.
Hardcore mode now disables the GPU force-video-timing setting. The console region can be changed while the emulator is running, and the update includes refreshed Spanish, Brazilian Portuguese, and Swedish Qt translations.
Platform builds and loading changes
The development build includes Windows x64, Windows x64 SSE2, Windows ARM64, Linux AppImages for x64, ARM32, and ARM64, plus a universal macOS archive. The README lists Windows 10 version 1809 or newer, Ubuntu 22.04-equivalent Linux for AppImages, and macOS 13.3 or newer as platform requirements. Older x86 systems that lack SSE4.1 can use the SSE2 build, though the project indicates that it has lower performance.
The update reorganizes dynamic library loading for components including SDL, image libraries, FreeType, PlutoSVG, and libzip. It also fixes libjpeg and libwebp loading regressions on Windows, adds library-path logging on Linux, and makes macOS bundle creation optional. These changes are aimed at making runtime library discovery and packaging behavior more predictable.
