This cannot be stressed enough:
If you follow the steps using your own dumped game, this falls under “fair use” in many jurisdictions for archival/backup purposes.
If you have a physical PS3 disc, use a compatible Blu-ray drive on PC with PS3 Disc Dumper to create an ISO. If you have a digital PS3 game (CFW PS3), copy the game folder (/dev_hdd0/game/XXXXX) to your PC.
Most modern PS3-to-PS4 PKGs do not use raw conversion scripts. They use a custom build of RPCS3 compiled for PS4 Linux or PS4 BSD.
Advanced users replace the libSceNpMatching.sprx and libSceNpScore.sprx with stubbed libraries to bypass PSN checks. This is why some "converted" PKGs require you to rename the EBOOT to boot_original.elf and place config .yml files in a specific folder (/data/RPCS3/config/).
Direct conversion is not possible. PS3 and PS4 have completely different architectures (PowerPC vs x86), so a PS3 .pkg will not run natively on a PS4, even if repackaged.
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.
The .pkg extension serves as a container archive for both consoles, but the internal architecture differs significantly.
Key Finding: A standard PS3 .pkg file cannot be installed or executed directly on a PS4. The operating systems do not share binary compatibility.
If you're looking for paper guides or manuals for your PS3 or PS4, you can usually find digital versions on the official PlayStation website or check eBay for physical copies.
Let’s immediately clear up a massive misconception. You are not turning a PS3 game into a native PS4 game. There is no magical compiler that rewrites Cell processor SPU code to x86-64 Jaguar code.
When a modder or tool creates a "PS3 to PS4 PKG," they are essentially building a wrapper. The PS4 is strong enough to run a PS3 emulator. The PKG contains:
In short: You are packaging a PS3 emulator and a PS3 ROM into a single installable file for a jailbroken PS4.
