No. A "mod menu" (in-game overlay for cheats, god mode, unlocks) requires running unsigned code, which is only possible on a jailbroken (CFW/HEN) PS3.
| Method | Models | Firmware | Difficulty | Permanence |
|---|---|---|---|---|
| CFW (Rebug, Evilnat, Ferrox) | CECHA–CECHK (NAND), CECHL–CECHQ (NOR, some) | ≤ 3.56 (factory) or patched | Hard (hardware flasher needed) | Permanent |
| HEN (Hybrid Firmware) + HFW 4.90+ | All FAT + most SLIM (not all 3000/4000) | 4.90–4.91 | Medium (web exploit) | Until reboot (re-enable via browser) |
| PS3HEN (ps3xploit) | Super Slim (late) – limited | 4.82–4.91 | Medium | Temporary |
Bottom Line: If you want mod menus, you need CFW/HEN. If you're on OFW 4.91 on a compatible model, follow PSX-Place guide. Otherwise, stick to Save Wizard or legit play.
