64 MB on PSP: Why It's Not Enough for Games & What You Need Instead

64 MB cannot hold a single playable PSP game. It's essentially obsolete for gaming.

• Typical PSP Game Size: 500 MB – 1.8 GB (UMD capacity: 900 MB single-layer, 1.8 GB dual-layer).
• What 64 MB Actually Holds: A few save files, some music tracks, a handful of photos, or a very tiny homebrew app.
• Minimum Practical Storage: 1 GB Memory Stick Pro Duo for a handful of games. 4–8 GB recommended for a usable library.

If you're still using a 64 MB Memory Stick (the original launch size), it's time to upgrade. Get at least a 2 GB genuine Sony or SanDisk Memory Stick Pro Duo—they're inexpensive and widely available.
