(Edit: To clarify, I meant overwriting the Steam version with the content from standalone version. I leave the original post intact, as the reply is about the original post.)
Someone suggested to download standalone RetroArch and overwrite with it the contents of the Steam installed RetroArch version to get the internal updater. And he claims that the Steam Cloud still works. Is this true? I have my doubts, because the standalone version does not have the Steam functionality builtin. Would anyone who knows this clarify this, please?
