@luis-fontes 2) you can't make partitions writable past rebooting the recalbox because that's the way recalbox protects itself against bad file handling or whatever, but doing as I said on the last post you will only have to go through the PuTTY thing only when you are saving the shaders/configs for a new system, you may even do It all in one session. Tell me if this worked for you, if you are using the same retroarch config for all systems its really very simple.
