Without VirtualQuery, a range no cached page table covers is looked up line by line in /proc/self/maps. A cursor in a gap between mappings never matched a line, so the scan parsed the whole file and then reported the rest of the range unmapped, including mapped pages after the gap. The scan now stops at the first mapping above the cursor, reports the gap up to it as inaccessible and continues from there, as the VirtualQuery path does with a free region. PPSA21564 queries near-null addresses (0x18, 0x30, 0x58) about 1500 times a second during resource capture; each of those parsed the whole maps file (about 5700 lines here) instead of stopping at the first mapping. Tests: agc_driver_graphics_tests describes three host pages with the middle one unmapped as two ranges, a query that starts in the gap as the page after it, and a near-null address as inaccessible.
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.
