#2096 keeps a copy of a storage image's guest bytes so that Refresh can compare memory the write watch does not cover. The host-import upload path takes that copy only when the range is unwatched, but the DCC fast-clear path took it on every upload. Reading the whole surface goes through the flush hook, so each 64 KiB block of a surface that a unit shadow covers recorded a publish and waited for the GPU. The clear path now resolves the surface's host import first (the import can unwatch the range, as a compared host-pointer import does) and takes the copy only when the range is then unwatched, like the import path. Write-watched memory, such as direct memory behind a dma-buf import, skips it; a range that is unwatched later re-uploads instead of comparing, as before #2096. agc_driver_dcc_keys_first_write checks that a fast-cleared upload keeps the copy exactly when its range is unwatched at that point. PPSA14632 (LEGO Horizon Adventures) on Linux, RX 9070 XT: the flush hook waited ~60,000 times per 10 s for these publishes (6.4 s), now ~3,500, and presents rise from ~24 to ~100 per 10 s.

About
Tool for automatic executables porting to Linux and Windows.
Includes a relinker that converts executable to the target system's native format and implementations of system prx libraries suitable for dynamic linking. No emulation or separate runtime process.

Status
* System libraries: percentage of the functions known to the project so far (declared in core/libs/prx), not of every PS5 system function. The total grows as more functions are declared.
Dreaming Sarah (2D platformer) runs at a stable 60 fps on a GTX 1050 Ti / i5-7500 3.4GHz.
Unsupported or unexpected states strictly throw std::runtime_error. what() is printed to stderr and the process terminates.
The shader recompiler successfully produces SPIR-V (validated via Spirv-Tools when built with ANYPS5_ENABLE_SPIRV_TOOLS).
Compatibility
See the game compatibility list for tested games and known issues.
Input mapping
SDL-mapped game controllers are supported, including analog sticks and triggers. Keyboard and mouse controls can be configured with an anyps5-input.ini file. See input mapping for the supported devices and configuration format.
