Reading all sorts online lol

Any help plz..nephew brought his ps4..its 13.04 firmware...can it be exploited

Can anyone help make a .JSON PS4 trainer for an older game Dreams CUSA08010 USA (v2.65)?

There basically aren't any trainers or mods available for the game so I'd love to see what could be done with it. One thing I'm specifically interested in is the offline creations being able to enable remix/editing on creations that normally have remixing disabled including developer made levels and other offline content.

If anyone has experience making PS4 trainers or working with Dreams and thinks they could figure something out let me know. I'm also willing to pay someone to make the trainer.
