KytyPlus v1.4

Download: KytyPlus-dev-2026-07-26-7952b64-windows-x64.zip

What's new vs v1.3:

Memory

• Windows fixed-address reservations now work for PS5 16 KiB pages that fall inside a host 64 KiB allocation granule (ported from upstream PR #101). Fixes hard failures seen as VirtualAlloc() failed 0x1e7 / pthread.cpp EXIT_NOT_IMPLEMENTED (upstream #100, #104)
• KernelMapDirectMemory / KernelMapNamedFlexibleMemory return EFAULT on a null address pointer instead of hard-crashing the emulator process

Launcher / window

• Controller and keyboard mapping moved into the Qt launcher GUI (no CLI-only mapping required)
• Graphics debug flags (graphics-debug-dump, spirv-debug-printf) exposed in the configuration dialog
• Fixed a crash when the window is minimized to a 0×0 surface/swapchain (notably during a title's splash screen): ignore degenerate resizes, clamp swapchain creation, skip present while minimized

HLE

• AppContentAddcontMount reports not-entitled instead of a fake OK with a phantom mount
• Registered an additional title's alternate NID for sceUserServiceGetUserName

Community / docs

• Compatibility and bug report forms now require OS / CPU / GPU / RAM
• Added a Playable status tier
• Closing an approved Compatibility report as completed auto-updates docs/COMPATIBILITY.md

Expectations

• Stability and boot-reach improvements, not a playability claim
• Verify with your own dumps/logs before reporting a title as working
