to anyone who's interested in the miyoo shit i'm on: the miyoo mini is too small imho. the miyoo mini plus is much better because it's bigger. these are the only two miyoo models which are compatible with onion os. you want onion os.
i've had one for over a year now? i love it. i couldn't recommend it more highly. the performance+quality to price+effort ratio is BIG NUMBER
the quality of the screen and buttons, two super important aspects of a gaming handheld, are unreal at this price point.
russ makes a great review and guide if you don't know what i'm talking about
buy it from their official aliexpress store: https://www.aliexpress.com/item/1005005215387485.html
and buy a cheap micro sd card of whatever size you'd prefer. don't overspend on something faster than the miyoo will be able to use. but big cards are good to fill with playstation games.
install this onion os operating system from here: https://onionui.github.io/
and you're good to go. it even comes with a screen protector.
you ever sshfs mounted your gameboy over wifi? you will. and the company that will bring it to you is miyoo
