Что такое формат файла PBP?
.pbp files are associated with the Sony PlayStation Portable (PSP) gaming console. The format, developed by Sony Computer Entertainment, is a proprietary binary container that packages an executable together with metadata, icons, background art and sound into a single file. The canonical filename is EBOOT.PBP - the entry the PSP's XMB menu launches directly.
Files with the .pbp extension can be used for distributing:
- installed PSP games and PS1 classic titles,
- game demos,
- applications and utilities,
- homebrew,
- system software updates.
.pbp is also a popular file format for installing exploits or custom (hacked) firmware.
Internally, every .pbp begins with the 4-byte magic \0PBP, followed by a version field and an offset table pointing to eight packed sub-files: PARAM.SFO (title and region metadata), ICON0.PNG, ICON1.PMF, PIC0.PNG, PIC1.PNG, SND0.AT3 (XMB menu music), DATA.PSP (the main executable) and DATA.PSAR (game data archive). Retail titles have DATA.PSP encrypted and signed by Sony's KIRK security engine, while homebrew .pbp files are typically unencrypted.
What is homebrew?
Homebrew is software developed by independent creators for devices that do not officially recognize it. PSP homebrew is distributed using .pbp files. Homebrew software can add new features to the target device or the ability to run certain applications. .pbp files allow users to install on their PSP such applications as ebook readers, file managers, media players, and emulators.
Beyond the PSP, the same .pbp container wraps PS1 classic games distributed on PlayStation 3 and PlayStation Vita. On PC and mobile, .pbp files can be opened through the PPSSPP emulator (available for Windows, macOS, Linux and Android) or unpacked with tools such as PBP Unpacker. PSP disc images are more commonly distributed as .ISO or .CSO files, while PSP plugins use the .PRX format.
Безопасность и защита
РИСК: MEDIUMA PBP is a package, not a self-running PC program, but homebrew EBOOTs are arbitrary PSP code from the community - run unknown homebrew only on hardware/emulators you're willing to risk, and prefer reputable sources. Retail EBOOTs are signed by Sony. Beware piracy: distributing copyrighted PSP/PS1 games as EBOOT.PBP is illegal in most places. The container itself can't infect a PC, but always scan downloads.
