would be possible to install Batocera on an x86 tablet and if so how?
I'm thinking a Linx Vision 8 or something along those lines, though the actual tablet doesnt matter so much
You can test If you can boot on USB/MicroSD card yes (because it's a Intel SoC with Windows 10, not ARM/Android)
But for me, i think boot is locked like a ARM Tablet (with a specific Bootloader/Recovery) and above all without BIOS
it may works if the tablet let you boot on your media.
the surface tablet by microsoft is known to work with batocera.
