Homebrew overview
What Homebrew Means on PSP
Homebrew is unofficial software written by the community and run on a PSP through custom firmware (CFW). Because CFW removes Sony's signature checks, the system will happily launch programs that were never approved by the manufacturer. This single change opens the door to a huge library of free tools, games, and utilities.
What You Can Run
- Applications packaged as EBOOT.PBP files, ranging from file managers to media tools.
- Emulators that turn the handheld into a NES, SNES, Genesis, or Game Boy machine.
- Plugins (.prx modules) that hook into games and the system menu to add features.
Why CFW Is Required
Stock firmware only boots officially signed code. Custom firmware patches the kernel so homebrew, plugins, and backups can load directly from the Memory Stick.
Where Things Live
Most homebrew is organized in clear folders on the Memory Stick. Applications sit under PSP/GAME, while disc backups go in ISO. Plugins typically live in SEPLUGINS and are toggled from the recovery menu.
Only install homebrew from sources you trust. Poorly written or malicious code can corrupt your Memory Stick or, in rare cases, brick the console.
With CFW active and a little organization, the PSP becomes one of the most versatile handhelds ever made.
