A developer said it takes 8 sec to boot.
You can also see it in the HardKernel video.
8 second boot is damn fast.
They're already sold out of pre-orders. Glad I got my order in before then!
A few things to note about this - it's designed to hacked-on. They set it so you can solder in a UART socket and cut the side of the case to access it. it also looks like they broke out the pins for you to solder in your own WIFI module should you so feel like it.
And they put just enough space between the hardware and the L1/R1 buttons to allow one to install their own L2/R2 buttons if they want to.
I've never quite seen such a clean board design in a retro-gaming handheld. The white board color makes it easy to figure this board out.
Mods for this one are going to explode.
And it's running Retropi/EmulationStation, which is going to make adding new software to it fairly easy.
I think the first mods seen will be how to replace the TFT screen with a compatible IPS one.
