DuckStation, the fast PlayStation 1 emulator for Windows, Linux, macOS, and Android, pushed a new build tagged v0.1-11609 on August 12, 2026, with most of the work aimed at people who record their sessions or play in fullscreen DuckStation v0.1-11609 release notes. This is a routine maintenance release rather than a compatibility breakthrough, but several changes touch daily-use features that emulation fans depend on.
The headline improvement lands in media capture. The build reworks how the emulator talks to Windows Media Foundation and ffmpeg, the two engines behind gameplay recording DuckStation v0.1-11609 release notes. The capture code now improves ffmpeg hardware encoding, tightens Media Foundation setup robustness, and clears its internal state before deleting an output file, so a failed recording no longer leaves a corrupted clip behind. The team also removed AV1 and VP9 from the Media Foundation option list and dropped support for ffmpeg versions older than 7.x, paring the code path down to configurations that still receive maintenance.
Fullscreen behavior gets steadier as well. The standalone fullscreen interface, used by players who want a console-like experience, received fixes for a debug assertion that could fire in single-threaded mode, a relaxed rule for closing the interface immediately after resuming a game, a new “None” transition effect, and queued texture recycling to smooth rendering DuckStation v0.1-11609 release notes. A separate Qt fix works around a border-drawing bug when the desktop interface runs fullscreen.
Under the hood, the core emulation logic picked up accuracy and stability fixes. The CD image reader gained support for non-mode2 and raw sectors plus a rewritten preloading memory image, while the CueParser now handles rarely used commands and the CD-ROM layer refactors how it reacts to invalid commands DuckStation v0.1-11609 release notes. The MMPX rendering path, which handles advanced blending, corrected a transparent-pixel bug and tightened floating-point tolerance, addressing visual glitches reported in pull requests #3774 and #3776.
Players who track achievements will see an animated unlock progress bar, and a bug that inverted the condition for flagging newly added games has been corrected DuckStation v0.1-11609 release notes. The memory card editor gained icon extraction and icons on its buttons, and the SDL game controller database was refreshed so newer pads map correctly.
Each change in the build is tied to a named commit in the project’s public repository, where GitHub documents how commit signatures confirm authorship GitHub commit verification documentation. DuckStation’s continuous integration, which the v0.1-11609 notes show bumping GitHub Actions’ checkout action to v7 in pull request #3775, runs on the same GitHub workflow ecosystem covered in GitHub’s “Harness Is All You Need” workflow, explained, and the full change list lives in the v0.1-11609 release notes.
For most users the practical move is simple: update on your next launch. The capture and fullscreen changes are the ones you will feel immediately if you stream or record, while the core fixes quietly improve disc-image handling and controller support.
