Can You Use Any Memory Card Brand in a PSP?

No. The PSP only accepts Memory Stick PRO Duo cards—a proprietary Sony format.

Why Other Cards Don't Work

• Proprietary slot: The PSP's memory card reader is physically and electronically designed exclusively for Memory Stick PRO Duo.
• Incompatible formats: SD, microSD, CF, and other cards will not fit or be recognized.
• OS limitation: The PSP firmware only mounts and accesses Memory Stick PRO Duo media.

Your Options

• Buy Memory Stick PRO Duo: Available at electronics retailers.
• PSP Go owners: Use Memory Stick Micro (M2) cards—smaller but compatible.
• PC transfer: Some games allow save backups to computer as a fallback.
