If your RG35XX does not have WIFI, you will hardly be able to download more themes for it, unless you download them from a page, like this one, and copy them to the card where you have Batocera installed. That is why we have created a new section, Themes for Batocera, in which we have added more than 50 themes that we have already tested and that we believe are “acceptable” to be able to see and use on the console. Many more work, but with graphic errors or with fonts so small that they make them difficult to read, so we have discarded them. Now available! May you enjoy them!
Do we still need to extract this?
Yes, in the themes folder
