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 PS3 PKG Editor and PS4 PKG Viewer let you save a package’s PARAM.SFO to open here. PS5 apps use param.json instead: see the PS5 App Editor.
