Hi guys. I feel bad to ask some basic questions.
I just installed image on SD card. My Pi2 recognized it. I configured network and now I don't know where to start.
1. I noticed that people on YouTube videos have nice themes for their PiPlay. Mine is very simplistic. Bunch of squares. How to change it?
2. Also, I don't want some of the emulators. How to edit the content? Is there a way just to plug micro sd into Windows computer and delete/upload files like roms?
3. I noticed that you can update them via WiFi. Is that the only way? How to upload covers with them? Is there any tutorial?
I uploaded some mame files in zip format, but they are not displayed in roms. How to upload mame roms?
4. Last question: I bought X-Arcade controller, that seems to be partially recognized by Piplay. Is there an option to use X-Aracde? Where?

Thank you for your help and that great program. I can't wait to fully use it.
