The entry stubs called the title's entry with rbp left as the process started it (0 on Linux) or as a loop counter left it (0 on Windows). The title's start code pushes rbp, so the frame-pointer chain of its main thread ended in a null frame pointer. Unreal Engine walks that chain to capture call stacks (for an ensure, for example) and reads the return address at [rbp + 8], so the walk read address 8 and crashed. Both stubs now push a zero frame record (saved rbp 0, return address 0) and point rbp at it before the call, so frame-pointer walks stop at the entry. The Linux stub pushes it below the aligned stack pointer, keeping the 16-byte alignment at the call. The Windows stub writes it into free slots of its own frame at rsp+0x40. PPSA15657 crashed in its stack walk at the title screen in about half of its runs.

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.
