The tool will read the PARAM.SFO file from the PS3 game to automatically grab the original Title ID (e.g., BLUS30000) and the official game title.

Launch the PS4 web browser, load your payload host, and select the payload.

Once the tool finishes, you will have a file ending in .pkg (e.g., MyGame.pkg ).

Audio tracks often stutter or fail to load if the original game utilized proprietary PS3 audio compression formats.

The most important thing to understand is that the PS3 and PS4 are fundamentally different machines. The PS3 uses a unique Cell Broadband Engine architecture—a PowerPC-based processor with one central Power Processing Element (PPE) and eight Synergistic Processing Elements (SPEs). The PS4, by contrast, uses a standard x86-64 AMD Jaguar processor—essentially the same architecture as a modern PC.
