Hacking a vita is so easy you do it straight from the console browser. I still can’t manage to get my DS properly hacked no matter how many guides I try.

I have only played the game in VR and loved it. The mod worked great for me a year or two ago so unless a patch went through it still should. Since you’re an experienced VR player I don’t think you’ll have too much issue with motion sickness. That being said it takes a lot to make me nauseous, so your results may vary. I think it’s an amazing way to get drawn into the world.
