@FoxBob79 with this script, you can install any version of batocera (x86, x86_64, rpi, odroid) on your hd, your sd card or a usb key.
it doesn't work because i've updated yesterday x86_64 and then, batocera-20170623.img.gz path is no more valid
can you retry please, it should work now.
the script :
download the file and install it on your device.
