The PSP **does not have a "Profile Menu."** Unlike PS3/PS4/PS5, the PSP (all models: 1000, 2000, 3000, Go, Street) uses a **single-system, single-account** model.
| Task | Where to Go |
|---|---|
| Change nickname / avatar | **Settings → System Settings → Nickname** (text only, 8 chars). No avatar. |
| Manage save data | **Game → Saved Data Utility** (or **Memory Stick → Saved Data**) |
| Account / PSN sign-in | **PlayStation Network → Sign In** (requires PSN account, firmware 3.80+) |
| Parental controls / password | **Settings → Security Settings → Parental Control Level / Change Password** |
| Ad-hoc / Infrastructure Wi-Fi | **Settings → Network Settings** |
| Theme / Wallpaper | **Settings → Theme Settings** (PTF/CTF themes on Memory Stick) |
| Language / Date / Time | **Settings → System Settings → Language / Date & Time** |
Summary: PSP = one user per device. For "profiles," use separate Memory Sticks or a PSTV/Vita (which *do* have profile switching).
