In most jurisdictions, downloading a ROM of a game from the internet—even one you already own physically—is technically a violation of copyright law. The only strictly legal way to acquire a ROM is by creating a backup (a "dump") of your own physical game disc using a PC CD/DVD drive. Sites like the Internet Archive operate in a legal grey area, relying on their status as libraries and the principles of digital preservation, but this does not make downloading from them definitively legal.

While this article focuses on technical archiving, you should only download or share PBP files for games you legally own. Many archive sites host or preservation copies , but copyright laws vary by country. If you care about preservation, consider:

A file (extension .PBP ) stands for "PlayStation Portable Binary" or "PBPack" . It was originally designed by Sony as a container format for downloadable PlayStation 1 games (called "PSOne Classics") to run on the PlayStation Portable (PSP) via its built-in PS1 emulator (POPS).

: You'll need a PS1 emulator that supports PBP files. Popular emulators include ePSXe, PCSX-R, and RetroArch.
