What to Do With PSP 3.71 M33 CFW Installed

You have a PSP with 3.71 M33 (classic Dark_AleX CFW). It's outdated but functional. Here's what to do:

Immediate Steps

1. Update to Modern CFW: 3.71 M33 lacks support for newer homebrew/ISOs. Install 6.61 PRO-C2 / Infinity / LME (see wololo.net guide for your model).
2. Backup NAND: Use PSPIdent or NAND Tool before any firmware change.

Capabilities (on Modern CFW)

• ISO/CSO Loading: Play backups from Memory Stick (via ISO Tool or native).
• Homebrew/Emulators: PPSSPP (PSP), RetroArch (NES/SNES/GBA/PS1), DaedalusX64 (N64).
• Plugins: CXMB (custom themes), TempAR (cheats), FuSa (TV out), Music.prx (background audio).
• PSN Access: PSNlover / PSN Patch plugins restore store access (limited).
