How to Add an Extras Tab on PSP

You cannot add an “Extras” tab to the PSP’s XMB (XrossMediaBar). The menu structure is hard-coded in the system firmware and cannot be modified by users, themes, or plugins.

What You Can Do to Organize Content

• Folders on Memory Stick: Create subfolders under /GAME/, /ISO/, /MUSIC/, /VIDEO/, /PICTURE/ to group homebrew, emulators, saves, etc.
• Custom Themes (.ptf / .ctf): Change background, icons, fonts, sounds—but tab count/order stays fixed.
• Homebrew Launchers: IrisMan, OneMenu, VitaShell (on Vita/Adrenaline) replace the game list view with a custom UI—still not a new XMB tab.
• CFW Plugins (Advanced): CXMB (custom XMB) can rearrange some top-level items on 6.60/6.61 PRO/ME, but adding a brand-new category requires deep firmware patching—high brick risk.

Recommendation

Stick to folders + a clean custom theme. If you need a radically different UI, run Adrenaline (PSP emulator on Vita) or PPSSPP on PC/phone where front-ends like RetroArch or Pegasus give full library management.
