fcntl and sceKernelFcntl answered EBADF (sceKernelFcntl threw) for every descriptor outside the libSceNet socket table, so files, pipes, directories and descriptors 0 to 2 could not be queried or changed. Observed: Yamagi Quake II (PPSA99007) stops with "Sys_Error: change stdin to blocking Bad file descriptor", from fcntl(fileno(stdin), F_SETFL, fcntl(0, F_GETFL, 0) & ~FNDELAY) (yquake2 src/backends/unix/system.c:81-86). Predicted from the titles' sources and decoded call sites: XPSemu (PPSA97358, 97 fcntl sites: F_GETFD 12, F_SETFD 20, F_GETFL 8, F_SETFL 9, F_DUPFD 1, F_DUPFD_CLOEXEC 7, F_GETLK 9) fails in qemu_init_main_loop, where its pipe2 (pipe plus F_SETFD FD_CLOEXEC) and glib's g_unix_set_fd_nonblocking (F_GETFL, F_SETFL) build the event notifier (util/event_notifier-posix.c:44-67); VLC (PPSA85300, 43 sites, F_RDAHEAD on every file it opens), RetroArch (PPSA99169, 17), Porpoise (PPSA99764, 13) and Ruffle (9) call it on files and pipes. The commands follow FreeBSD 11.4 kern_fcntl and kern_dup (sys/kern/kern_descrip.c:479-799, 812, release/11.4.0 8c639945): F_GETFD/F_SETFD keep the close-on-exec flag per descriptor, F_GETFL reports the host access mode with the status flags, F_SETFL changes only O_NONBLOCK, O_APPEND, O_ASYNC, O_FSYNC, O_DIRECT and FRDAHEAD, F_DUPFD/F_DUPFD_CLOEXEC give the lowest free descriptor at or above the start through dup (EINVAL for a negative start), F_DUP2FD goes through dup2, F_RDAHEAD/F_READAHEAD set FRDAHEAD on files (EBADF on pipes, ENOTTY elsewhere), and unknown commands fail with EINVAL. Status flags live in a guest table shared by dup, dup2 and F_DUPFD like an open file description. O_NONBLOCK switches a pipe (PIPE_NOWAIT on Windows, where an empty read and a full write now report EAGAIN; the host flag on Linux). Record locks use the host POSIX locks on Linux and throw on Windows. Changes the host cannot model throw naming the flag and descriptor kind. Sockets keep their path unchanged.

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.
