Since you cannot compile a native PS4 .pkg file out of a PS3 game folder, the definitive workaround discovered by developers involves installing a directly onto a jailbroken PS4, then utilizing the open-source RPCS3 emulator . Prerequisites & Tools Needed
A USB Hub (to connect a mouse, keyboard, and external drive simultaneously).
Because the PS4 cannot run PS3 code directly, you have to run a full PC-style emulator inside a Linux environment on your console. Requirements
to convert disc-based folder games into installable PKG files for easier access on a PS3 XMB.
: A jailbroken PS4 (running GoldHEN), a Linux-bootable USB, and the RPCS3 emulator. convert ps3 games to ps4 pkg
Often, users looking to "convert to PKG" are actually trying to make their PS3 games compatible with a jailbroken PS3 (HEN/CFW), not a PS4.
Converted games can take up significant storage space, and large games might need to be split during the pkg creation process.
Necessary for running the conversion tools.
If your interest extends to PS2 games, you have more options. The homebrew community has developed tools like that can convert PS2 ISO files into FPKG packages that run natively on jailbroken PS4 and PS5 consoles. This works because Sony included PS2 emulation capabilities in the PS4. However, this approach only applies to PS1, PS2, and PSP games—PS3 remains the exception. Since you cannot compile a native PS4

Q: Can I convert PS3 games to PS4 PKG files using a Mac? A: Yes, some conversion tools are available for Mac, but the process may vary. Research specific tools and guidelines for Mac users.
This difference is fundamental. A PS3 game is written to speak a language that only the Cell processor can understand. The PS4's x86 chip has no ability to interpret that native PS3 code. To run PS3 code, the PS4 would need a full emulator, a complex software layer that translates PS3 instructions on the fly. Sony never included a PS3 emulator in the PS4, likely due to the immense difficulty and performance penalty of such a task.
In short, a "PS3 to PS4 PKG Converter" is currently a myth. While some of Sony's official "Digital Upgrade Program" content allows for playing certain PS3 games with improved performance, the core action of universally converting a PS3 game into a playable PS4 file remains impossible. Converted games can take up significant storage space,
deserves special mention as a comprehensive solution. It supports creating PKGs for PS1, PS2, and PSP games on your PS4, as well as downloading game patches, sending payloads, and managing backups across PlayStation platforms.
Before starting, it is vital to understand what happens during this conversion process. The PS4 does not possess the hardware architecture to natively run or perfectly emulate the complex "Cell Broadband Engine" processor of the PS3.
If your game is currently in .ISO format, extract it using a tool like WinRAR or 7-Zip into a dedicated folder.
