PSP Homebrew refers to unofficial software created by independent developers for the PlayStation Portable. It transforms the PSP from a game-only device into a versatile handheld computer.
Modified system software (PRO CFW, ME/LME) enables homebrew, ISO/CSO loading, plugins, and custom themes. Installation requires a hackable PSP model (1000, 2000 non-TA088v3, 3000 early models, Go) and specific firmware versions (6.60/6.61).
Communities like r/PSP, wololo.net, and PSP-Hacks offer guides and support. Proceed with caution, respect copyright, and enjoy one of gaming's most vibrant homebrew scenes.
