Difference Between Memory Card and Memory Stick on PSP

The PSP **only uses Memory Stick** (Sony proprietary). There is no "memory card" slot.

Memory Stick PRO Duo	32 GB	Standard for PSP-2000/3000/Go
Memory Stick PRO-HG Duo	32 GB	Faster transfer (Mark2 certified)
Memory Stick Micro (M2)	16 GB	Requires M2→Duo adapter
Memory Stick PRO (original)	4 GB	PSP-1000 only (no Duo slot)

SD/microSD cards **do not fit** and **will not work** without a hardware mod (custom firmware + adapter).
Format in PSP: Settings → System Settings → Format Memory Stick.
MagicGate DRM support required for some games/saves—use genuine Sony/SanDisk sticks.
