The problem with H&S injection is that Parental controls won't lock him out of it and there's still the chance he might stumble upon it by accident.
Anyways, my repack with prebuilt icon file was a success. I modified the source code to use a prebuilt bin file instead of building the icon from a png file as it normally does and confirmed that parantal controls locks me out of it without knowing a PIN as intended. (I simply had to enable game ratings when building the icon. Was easy.
)
I'll upload it shortly.
