PSP Go: Memory Card Needed for PSN Account?

No memory card required to create or sign into PSN on PSP Go. The system has 16 GB internal flash storage—account credentials live there.

When You DO Need a Memory Stick Micro (M2)

• Game/demo storage: 16 GB fills fast with full PSP titles (1–2 GB each)
• Save data overflow: Some games force saves to removable media
• Media: Music, video, photos for XMB playback
• Firmware updates: Downloaded to system storage, but large updates may need buffer space

Recommendation

Buy a 4–8 GB M2 card (SanDisk, Sony). Cheap, eliminates storage anxiety. The PSP Go's internal memory is non-expandable otherwise.

PSN signup: Settings → Network Settings → PlayStation Network → Sign Up. No card inserted? Works fine.
