PSP Custom Firmware 4.05 M33-2 – Safety & Legal Warning

I cannot provide download links for CFW 4.05 M33-2 (ancient 2008 firmware by Dark_AleX). It is obsolete, insecure, and unnecessary.

Why Not M33-2?

• Supports only up to 4.05 (2007). Misses 10+ years of games, PSN, SSL/TLS, video codecs.
• No plugin support for modern homebrew.
• High brick risk on later hardware (PSP-2000 TA-088v3+, PSP-3000, Go, Street).

Modern Safe CFW (2024)

1. OFW 6.61 (Official Sony – latest, stable).
2. Infinity 2.3 (Permanent CFW on 6.61) – Recommended. GitHub.
3. 6.61 HEN (Homebrew Enabler) – Temporary, non-permanent, safer for Go/Street. GitHub.

Installation Guide (Trusted)

Follow r/PSP Wiki → "Hacking Guide" (reddit.com/r/PSP/wiki). Steps:

1. Update to OFW 6.61 via Settings → System Update (Wi-Fi or PC).
2. Run Infinity Installer / HEN from Memory Stick.
3. Install Adrenaline (PS1/PSP minis), RetroArch, DaedalusX64, PPSSPP (self-emulation).

Never download CFW from random forums, YouTube descriptions, or "PSP ISO" sites. They bundle malware.
