Converting a PBP (typically a PSP EBOOT) to an ISO for patching is a two-step process: you must first extract the disc image from the PBP container and then apply your desired patch to the resulting ISO. 1. Extract PBP to ISO

If you are reading this, you likely have a PBP file—perhaps a game you downloaded for the PlayStation Portable (PSP) or PlayStation Vita—but now you need a standard ISO file. Why? Perhaps you want to burn it to a CD for a real PS1, or you are using an emulator like ePSXe, DuckStation, or RetroArch that prefers raw bin/cue or ISO structures.

To understand the conversion, one must first understand the PBP’s purpose. Sony introduced the PBP format for the PlayStation Portable (PSP) to run official emulated PSX games (called "PSOne Classics") directly from the PSP’s Memory Stick. A PBP file is essentially a compressed, multi-disc container. It can hold up to five ISO images (for multi-disc games like Final Fantasy VII or Metal Gear Solid), along with metadata, icons, and recovery data. Crucially, the PBP format strips away certain low-level structures of an original ISO—such as error correction codes (ECC/EDC) and precise subchannel data—in favor of smaller file sizes and faster access on the PSP’s slower optical drive emulation.
If you are doing this to play a patched game on a physical PSP or Vita (via Adrenaline), you’ll need to turn that ISO back into a PBP.
