I am a Miyoo Mini V2 user and I love the heck out of it, but stopped using it since I knew about Retroachivements (because of the lack of wifi signal)… Tbh the plus model seems like a good option to me as it integrates that hardware feature… But I’m trying to keep my collection simple (more like I have too, I am poor).
Definitely having an Android phone will be a better option for emulation than what we currently have in the market, but these damn Chinese consoles have their charm!
Also I would not use my main Android for serious gaming/emulation as I’m a battery freak and seeing it going lower than it normally does would bring a bit of anxiety to me.
Purchasing a separate Android device and attaching it to my Razer Kishi sounds like something feasible to me (or re use my current one when I’m done with it, this is my first Android device and has a SD 865).
Anyway all the SBC gaming world is amazing to me and that will never stop.
