The PS4 does not natively emulate PS3 hardware. This process only works for specific games that have been officially ported by Sony (via "PS2 Classics" emulation on PS4, or the very specific PS3-to-PS4 port programs) or, more commonly in the homebrew scene, using the emulation layer on the PS4 to run PS2 games extracted from PS3 ISOs.
The console must run a custom firmware or exploit environment (such as GoldHEN) to install and execute unofficial .pkg files.
: PS3 games are designed for a specific operating system and memory structure (512MB total) that does not align with the PS4's 8GB framework. The "Linux/RPCS3" Workaround convert ps3 games to ps4 pkg
Instead, this process wraps a PS3 game ISO into a PS4 package structure, relying entirely on the built-in used by the PS4 to run PlayStation 2 Classics. Consequently, this method is limited exclusively to PS3 games that were officially re-released as "PS2 Classics" on the PS3 PlayStation Store.
Unlike the PS5 (which includes PS4 backward compatibility through hardware-level support), the PS4 was never designed to run PS3 software. Sony itself handles PS3 backward compatibility through cloud streaming via PS Plus Premium, not native execution. The PS4 does not natively emulate PS3 hardware
