Converting PBP to ISO is essentially taking the game out of the PSP "box" and putting it back into a standard CD "case." The conversion process is handled by a legendary tool in the emulation community known as PopStation (or its graphical variants like PSX2PSP). And Damages De Leon — Torts
In these cases, specialized extraction tools are required to split the PBP back into separate files: Disc1.iso , Disc2.iso , etc. Converting PBP to ISO is a process of unpacking history. It transforms a file optimized for a specific handheld device into a universal format that can be preserved, burned to disc, or played on modern high-fidelity emulators.

The format is native to the Sony PlayStation Portable (PSP). It wasn't designed for PCs; it was designed for the PSP’s internal architecture. When Sony released the PSP, they wanted gamers to buy and download classic PS1 games from the PlayStation Store to play on the go. These purchased games were packaged as PBP files.
Interestingly, PopStation was originally designed to do the reverse —it was created to turn ISOs into PBP files so that custom firmware PSPs could run backups. However, because the process is reversible, the same tools can extract the ISO from inside the PBP shell. If you have a PBP file and need an ISO, here is the most straightforward way to perform the extraction:
A PBP file is capable of holding multiple discs inside a single file. This was a brilliant feature for the PSP—you could switch "discs" via a soft-menu without physically swapping cartridges. However, a standard ISO file cannot hold multiple discs. If you try to convert a multi-disc PBP to a single ISO, it often fails or corrupts the data.
One fascinating complication arises with games that span multiple discs, like Metal Gear Solid or Final Fantasy VIII .
Just remember: the resulting ISO file will be significantly larger than the PBP file. The PBP format uses heavy compression to fit onto the PSP’s limited Memory Stick, so "unzipping" it back to ISO restores the file to its original, full-sized glory.
