I don't have high expectations for the Miyoo Mini, but I really like the looks particularly with the screen so went ahead and ordered one at the low risk price of $52 on AliExpress.
MIYOO Global Store
It's likely running the same OS as the S30 which I was not a fan of so we'll see if custom options like Simple30 become possible. Power-wise this handheld should be able to run up to PSX (PlayStation 1)...
It appears the Miyoo Mini does have a safe shutdown so this may also be an upgraded version of the S30 OS too. My expectations aren't huge here for the price so hopefully it ends up being better than the price.
