How to Put a Disc in a PSP? You Can't – PSP Uses UMD, Not Discs. Here's How to Play Games Today

PSPs do not use discs. They use UMD (Universal Media Disc)—a proprietary optical format in a sealed cartridge.

Playing PSP Games Today

• Original hardware: Insert UMD into the drive slot (left side on 1000-3000, top on Go).
• Digital (PS Store): Purchase/download to Memory Stick (PSP) or internal storage (Go). Store closed 2016; prior purchases only.
• Emulation (PC/mobile): PPSSPP runs ISO/CSO files. Legal only if you dump your own UMDs. Downloading ISOs = piracy.

No disc slot exists on any PSP model—only UMD.
