As we thought, the Q400 is now shipping!
This RK3128 powered machine runs on RetroArch (we think!) and sports a high resolution 800×480 panel, as well as dual analog sticks and four shoulder buttons. The Q400 costs a very reasonable $80 shipped, and should have far better performance than the RG350 and PocketGo v2 handhelds of 2019.
It will be really interesting to see where developers can take this machine this year. I should have mine sometime in May, so will be sure to let you know what I think of it. For more info, check my other post here.
