Well, You're kinda wrong and right.
1. The PSVR Most Likely Can play this, but it requires a PC
2. The PSVR CAN interface with a PC, but it requires some software to set it up
3. You are right about the PS4 requiring signed code, It's standard practise for all console developers to add an encryption method to prevent hacking.
4. There Is hacks for the PS4, but Sony is starting to fix all of the bugs that those hacks take advantage of.
5. The Game is most definitely not designed for the PSVR since they developed it with an Oculus Quest/Quest 2 (or rift idk I don't remember much about the video)
