@notechskill said in "B" turns to "X" on second controller after restart:
@danielmewhouse just to be clear. On my keyboard hit f4 and go to the command prompt and type in exactly what you have typed out there?
I know you purposefully selected a username to proclaim your skill level on tasks like this, but I am hopeful this is more of a tongue-in-cheek moniker, as you clearly know enough to image an SD card, swap Pi Zeros, and you figured out how to exit to a command prompt.
Yet, I think you need to set your expectations appropriately for much of the help you will get here. It is generally expected (and required per the agreement in the forum sign-up) that you have read the documentation, that you explain the source and version of your software setup. I scrolled back through the questions and responses and I cannot tell what you are running. Is it an image you downloaded here?
Something else to be aware of that isn't obvious when you look at the breadth of emulation coverage in RetroPie and you read about all of the development effort is the fact that the Pi is still an educational platform. The RetroPie image and accompanying script does make a lot of the installation steps much easier than it would be if you had to figure all of it out on your own, but it is by no means as easy as a commercial solution--and it was never meant to be. I make this statement not to intimidate, but to explain that a lot of the answers you get here will require an investment in understanding the environment. For example, when someone suggests you check a file, or edit a configuration in a given folder, it is expected that you will know how to navigate to that folder, either over a network connection from another computer, or through commands at the command line. Rarely will folks give you every last keystroke. You may in fact need to google answers about how to navigate in Linux, how to change directories, copy files etc.
There are many guides that aim to streamline steps that would otherwise be a barrier to people with no tech skills, but troubleshooting is always going to be unique to your configuration. I say it a lot on the forum to newcomers that almost none of us uses the same hardware. By committing the Pi you are also committing to learning--a process that is supposed to be fun.
With that said, welcome to the forum! Please, do provide more background about what you are building, how you setup RetroPie and other details requested here. We are genuinely interested in your project and want to help, but most of the time it will be helping you help yourself.
