I’m running beta 3 on a Pi 1 but all of a sudden some of the icons in emulation station at the bottom of the screen have turned into blocks. Opening some of the rom selection screens for each emulator shows either a black screen or it just doesn’t look right – it’s as if some of the assets are missing or corrupt. Returning back to the main ES screen makes it turn black and pretty much unresponsive. Any ideas on how to solve this gratefully appreciated. Thanks in advance.
