Just got this bad boy yesterday and I'm like a kid at Christmas! ๐ The delight I felt firing up my old love, Desert Strike... Goosebumps! Seriously impressed with this bit of kit, and I'm enjoying exploring the options as much as the many many games! The effort put in by the community with GarlicOS and the ROM packs is simply magnificent.
Honestly I might pick this one up just for the size upgrade. Seems a bit nicer for longer sessions. Battery life okay?
If you like the Miyoo Mini, you can check out Miyoo Mini Plus - it's a bit more expensive, but from what I heard it's manufactured a little bit better and has better triggers. I really like mine.
Unfortunately right now the Miyoo devices are nigh impossible to purchase.
