I have a 4.55 ps4 and i think we can hack the ps4 on that firmware soon, but what we can o with that, the only hack for ps4 is on 1.74 right? but what can you do with that? can we play backups? run homebrew apps, or emulate any other consoles? I did't see too much news about ps4, like apps or homebrews for ps4,,, so I want to know that.
