I have an SD card loaded with video games retro pie attract mode remastered. Everything works fine on my (old) rasp 3. However, I just bought the new B+ model and it isn’t working. When I plug in the B+, there is only the lightening bolt icon in the top right corner and nothing happens. I’m using the same 5V, 2.5amp power supply, so not sure why power would be an issue. I’m guessing there is some sort of small change I need to make in the config text or something. Please Help!!!
