I started with the USA AC adapter. I like that it’s Eco-friendly and saves money, but it has some convenience problems. For example; I want to play lying down, but the only outlet in my room is all the way across from my bed. Also if I built the head strap from the workshop, an adapter would interfere with the strap making the VB ”portable”. I also want the USA VB box, because North American Virtual Boy boxes have epic looking box art! 😎
