@voljega@Substring thanks replying so quickly and for the information. This is information, while disappointing for my project, is understandable. I think I'm going to have to investigate other options in this case.

@lendário this line is wrong there is no /storage on recalbox. That's an excerpt from lakka. Better check the RA cfg file in the share_init, or retroarchcustom.cfg.origin in the folder of your files
@alexander-tolstykh that's always a bad idea to unplug the power without shutting it down, like any operating system, you may corrupt your data. And yes, because wifi management has been reviewed to allow network share over wifi, now you must shutdown your system properly to keep your wifi settings.
