PARAM.SFO Editor

An online PARAM.SFO editor for PSP, PS3, PS Vita and PS4 homebrew. Open a PARAM.SFO and read every key: title, title ID, category, app version, the firmware the software asks for, parental level and the rest, the common ones explained in plain English. Change a value within the space the file sets aside for it, add or remove keys, and download the file again; an unedited file comes back byte for byte identical.

It does the job of the old SFO editors and of the SDK tools mksfo, mksfoex and vita-mksfoex, with nothing to install. Templates start a new PSP, PS3 or Vita PARAM.SFO from scratch. The EBOOT.PBP and VPK tools edit the PARAM.SFO inside those files directly, and the PKG tool lets you save a package’s PARAM.SFO to open here. PS5 apps use param.json instead: see the PS5 App Editor.
