During the launch window of the PlayStation 4 (approx. 2013–2015), several third-party titles released on both PS3 and PS4 (e.g., Destiny, Call of Duty: Advanced Warfare, Assassin's Creed IV: Black Flag).

Note: Only games with minimal PS3-specific syscalls may work.
Because manual conversion is a nightmare of EBOOT decryption and library relinking, most users rely on community "releases." Look for the "PS3toPS4" section on popular PS4 scene forums (like PSX-Place or Wololo). Reputable modders like Opoisso893 and Zer0xFF have released prepackaged PKGs of games that actually work:
Note: You must still have the PS3 game data to legally merge with these launcher-only PKGs. ps3 to ps4 pkg
Using the Python script create_project.py:
python create_project.py --name "My Game" --game-id BLUS12345 --eboot "path/to/decrypted/EBOOT.BIN" --gamedata "path/to/PS3_GAME/USRDIR"
This script generates a folder structure with:

These games are stuck on the PS3—unless you use the PS3 to PS4 PKG method. By converting them, you can:
.gp4 project.505 (for 5.05) or 900 (for 9.00). Lower is safer for compatibility.As of 2025-2026, the PS4 homebrew scene has slowed because firmware exploits beyond 9.00 are rare. Newer PS4s cannot jailbreak. Thus, PS3 to PS4 PKG conversion is not advancing rapidly.
However, the PS5 homebrew scene (though limited) may eventually offer better SPU emulation. Some developers are working on “PS3_Emu” payloads for PS5’s higher clocks, but a public release is years away. PKG files are package files used by Sony's
For now, the method described here is as good as it gets—a fascinating technical achievement but a practical dead end for most gamers.
Title: The Truth About Converting PS3 Games to PS4 PKG Files
There is a common misconception in the modding community that you can simply take a standard PlayStation 3 game file (ISO) and "convert" it into a PlayStation 4 package (PKG) file. Unfortunately, this is not how the technology works.
The PS4 cannot natively play PS3 games because it uses a completely different system architecture (x86 vs. the PS3’s complex Cell processor). When you see a "PS3 to PS4 PKG," you are actually looking at a PS2 Classics wrapper or a specific, officially ported version of a PS3 game that Sony released on the PSN store (known as a "PS Now" or "Remaster" PKG).
Standard PS3 disc backups cannot be converted into playable PS4 PKGs. To play PS3 games, you must either use a PlayStation 3 console, utilize Sony’s PlayStation Plus Premium cloud streaming, or play a specific native PS4 port of the game.
