SELF File – What is .self file and how to open it?

SELF Files: An Overview

A SELF file is a file format used on Sony PlayStation Portable (PSP) and PlayStation Vita (PS Vita) handheld gaming consoles. It is a signed executable and linkable format that contains executable code and data for PSP and PS Vita games and applications. SELF files are essential for running software on these platforms and are typically packaged in a PBP or EBOOT.PBP file format, which also includes other necessary files for the game or application.

Technical Details of SELF Files

SELF files are based on the ELF (Executable and Linkable Format) used in other operating systems. They include information such as the game’s code, data, resources, and metadata. The signing component of the SELF format ensures that the file has not been tampered with and is authorized by Sony. This signing process helps protect the PSP and PS Vita ecosystems from malicious software and piracy. SELF files can be created using development tools provided by Sony, allowing developers to create and distribute games and applications for these platforms.

Opening SELF Files on PlayStation Systems

To open SELF files on PlayStation systems, you require the system’s official firmware or a custom firmware (CFW). A SELF file is a signed executable for the PlayStation 3 console and can be run directly on the system if it is signed by Sony. On the PlayStation Portable (PSP) and PlayStation Vita handheld consoles, SELF files are installed to be launched as applications.

To open a SELF file on a PlayStation 3 console without CFW, you need a hacked console and a program called PS3xploit. With CFW, you can directly install SELF files to the console. On the PSP, you can install SELF files using a USB drive or a memory stick. For the PlayStation Vita, you need to use a custom firmware or homebrew software to open SELF files.

Opening SELF Files on Other Devices

While SELF files are specifically designed for PlayStation systems, it is possible to open them on other devices with the help of emulators. An emulator is a software program that mimics the hardware and behavior of another device, allowing you to run programs designed for that device on your own computer.

Several emulators exist for PlayStation systems, such as PCSX2 for PlayStation 2 and PPSSPP for PSP. These emulators can be used to open and run SELF files on Windows, Mac, and Linux computers. To open a SELF file using an emulator, you need to download and install the emulator, then locate the SELF file and open it within the emulator. Some emulators may require additional setup or configuration before you can run SELF files.

Signed Executable and Linkable Format (SELF)

The Signed Executable and Linkable Format (SELF) is a proprietary executable and linkable format developed by Sony Computer Entertainment for the PlayStation Portable (PSP) handheld video game console. SELF files are used to distribute and load executable code on the PSP. They are similar in concept to ELF (Executable and Linkable Format) files used on other platforms, but they include additional features to support the unique security and portability requirements of the PSP.

SELF files store compiled code, data, and metadata necessary for running a program on the PSP. They are typically digitally signed by Sony Computer Entertainment to ensure their authenticity and prevent unauthorized modifications. The signing process involves generating a digital signature that is included in the SELF file and verifying against a public key stored on the PSP. This mechanism helps to protect the PSP from malicious code and ensures that only authorized software can be installed and executed. SELF files can also include additional sections for resources such as images, fonts, and sounds, making it convenient to distribute a complete application in a single file.
