Awhile back we reported on a PS3 System File Editor followed by a Linux Edition, and today JizzaBeez has made available his own version of a PS3 PARAM.SFO Editor homebrew application.
To quote: I decided to fully research the PARAM.SFO file and make a tool to edit any aspect of it.
And it seems to work really well as far as reading/writing, although I don't have a PS3 to test the saves...
So if anyone experiences a problem then give me all the details...
How to use:
1) Open a PARAM.SFO file in the editor.
2) Right-Click to edit, then save.
