Release History
October 20, 2026 — xbox-1.1.26293.2037
Shader, audio and GPU compatibility fixes
What changed: Updated shaders and NGS2 audio, added handling for user clip planes and ordered compute passes.
Why it matters: Fixes some emulator-side failures, but does not establish that a particular PS5 game is now playable.
Action required: After upgrading, remove compiled shaders once: Settings → Developer → Remove compiled shaders.
October 19, 2026 — xbox-1.1.26292.1807
Black in-game screenshot fix
What changed: Fixed screenshots captured during gameplay appearing black.
Why it matters: Corrects screenshot capture. It is not a general fix for a game showing a black screen.
October 19, 2026 — xbox-1.1.26292.1138
Detailed overlay and upstream improvements
What changed: Added more detailed CPU/GPU/RAM information, local co-op updates and shader-related changes.
Why it matters: Makes diagnosis and testing easier; does not automatically add playable titles.
Action required: This release also instructs upgraders to clear compiled shaders once.
October 18, 2026 — xbox-1.1.26291.1739
Faster loading and rendering work
What changed: Improved .zar loading, memory-saving defaults and handling of several Direct3D 12 rendering cases.
Why it matters: May reduce specific failures or delays; game-by-game improvement still needs Xbox testing.
October 13, 2026 — xbox-1.1.26286.857
Keyboard, trophies and refresh-rate options
What changed: Added on-screen keyboard support, in-game trophy access, 30/60/120 Hz display options and fixes.
Why it matters: Improves app interaction. A 120 Hz display setting is not a claim of 120 FPS gameplay.
October 11, 2026 — xbox-1.1.26284.2244
Overlay settings and trophy notifications
What changed: Added in-game overlay controls and trophy notifications.
Why it matters: Improves how users view emulator status and in-game notifications.
October 11, 2026 — xbox-1.1.26284.1505
Early public Xbox Developer Mode build
What changed: Published an experimental Series X|S package with Device Portal installation instructions.
Why it matters: Provides the first documented public installation route; the published build excludes Xbox One.
Before You Update
A new PS5X version does not mean all PS5 games now work. Only a game-specific Xbox test can establish compatibility. Check the instructions attached to the exact build you are installing; some releases require clearing compiled shaders once after upgrading.
