How to Put PSP Games from Disc (UMD) onto Your PSP Memory Stick

You cannot simply copy files off a UMD. UMDs use a proprietary format with encryption; the PSP's firmware blocks direct file access.

Legal Workflow (Requires Custom Firmware)

1. Install CFW: 6.61 PRO-C2 or Infinity on any PSP model (1000/2000/3000/Go/Street). Follow hacks.guide.
2. Insert UMD.
3. Launch UMD Dumper or ISO Tool homebrew.
4. Select "Dump to ISO" → saves GAME.iso to ms0:/ISO/.
5. Play from Memory Stick: ISO appears in Game menu; faster load times, saves UMD drive wear.

Critical Legal Note

Dumping is legal **only** for games you physically own, for personal archival (varies by country—check DMCA §1201 / EUCD). Downloading ISOs of games you don't own is piracy.

Alternatives Without CFW

• Buy digital versions (PSone Classics, PSP Minis) from PlayStation Store via PS3/web.
• Play UMD directly—no installation needed.

CFW also unlocks homebrew, emulators, plugins, and themes—worth it for enthusiasts.
