Tried another SD card, same thing. Deleting os files lets me have the standard ED64 wallpaper but when changing wallpaper it goes to this same background. It will do the loading for when i try to load a number of different N64 games and black screen. Plays NES games just fine. I've been inactive for a while and it's probably been about 20 months since I've last powered on my ED64, so that might be a factor. Not sure what to do from here Any help super greatly appreciated!

I had the same issue after installing an OS update. Had to revert back to a working one and that did the trick. Did you update the OS?
