No "pipe" key - can't run setup!

Hi all, I’m new here. I’ve searched and searched, but can’t find an answer.
I’m setting up my picade, and have been mostly successful, except at the very end!

When I boot the picade, it keeps saying no controller found (I only have a keyboard for now). I continue on with the setup, assigning random console-controller-based keys.
Now that the keys are all screwed up, how can I re-assign them?

More importantly, at the prompt, the instructions have me put in this line:
curl | bash

With my keyboard layout I can’t find the pipe key! it’s usually with the backslash right above the Enter key, but it’s not there.

I’m almost there - help!
Thanks in advance

Found the issue, it was localization.
After a couple of hours, I found where the localization settings are, and switched it to my keyboard.
After that, I was able to run the setup script successfully.

Now, when it boots, there’s a pretty multicolor screen, then blackness.
Utter, unending blackness…
