Playing ISO Files on PSP with 5.03 ChickHEN R2: Required Tools & Risks

The PSP's native firmware does not support ISO files directly. ChickHEN R2 enables homebrew, but you'll need additional tools to play ISOs.

Required Homebrew Launchers

• ISO Loader / Prometheus ISO Loader: Browse and launch ISO/CSO files from the XMB.
• PSP ISO Tool: Convert ISOs to compressed CSO format to save Memory Stick space.
• OpenPSP / TN-V: Advanced custom firmware (CFW) environments with broader compatibility.

Important Considerations

• Only use ISOs from games you legally own to avoid piracy.
• Backup your Memory Stick before installing any homebrew.
• Compatibility varies; some games require specific CFW versions (e.g., 6.60 PRO-C2, ME/LME).
• Performance may differ from UMD: longer load times, occasional audio/video glitches.

For the best experience, consider installing a permanent CFW like 6.61 Infinity on compatible models (1000, 2000, 3000 with hackable motherboard).
