@Substring Not sure how you let me down? It's amazing to have help with this!

Here are my results:

cat /boot/recalbox-boot.conf
internal=/dev/mmcblk0p8
sharedevice=INTERNAL

/recalbox/scripts/recalbox-mount.sh "ext4" 1 "/dev/mmcblk0p8" /recalbox/share
mount: mounting /dev/mmcblk0p8 on /recalbox/share failed: Invalid argument

@Substring I'm not showing that script on my system:

/recalbox/scripts/recalbox-part.sh "share_internal"
-sh: /recalbox/scripts/recalbox-part.sh: No such file or directory

Let me know if you were looking for something else

Still looking for a little help: twice now I've got through the install process, added all my roms, added the pin 56 switch line to the config, added my LED config (dtparam=act_led_gpio=22) to /boot/config.txt ...and both times after a few cold reboots all my changes are gone. Recalbox reverts back to the default rom set and there is no room to add roms to my shared folder. I briefly saw some text flash on the screen but was unable to take a pic, something about ext4... partition problem I guess?

This is on the latest build of Recalbox, Pi Zero, generic Amazon SNES USB controller and a Logitech K400r wireless keyboard / mouse combo.

Anyway if anyone has a suggestion or can see what is causing the problem I would appreciate the help

I'm not exactly sure what happened, my daughter was playing the recalbox I had set up and did not turn it off. When I turned it on again, the system was locked up and not responding via SSH. I had to pull the plug. When the system rebooted all of the roms were gone, the original homebrew roms were back and it didnt recognize my gamepad, essentially it reverted back to the original default install.

Is this SD card corruption? was something triggered when used? I was on the newest build, had just updated via the built in system. Thanks
