Three player button/joystick setup is not configured properly - don't have a linux computer to edit the file on. Is there another way?

Hello, forgive me in advance as I'm about 1 week into this community as I recently purchased a multicade on Facebook. It has a three player setup, but only the middle joystick is working to play games. Since my button setup only has 2 buttons each, I don't have an 'x' button to use Hotkey+X to configure the controllers as I've read elsewhere. When I shut down the machine and remove the SD card, it doesn't show up on Windows, and it seems to be missing files when opening on my Mac. I assume the file is formated to Linux, but I dont have a linux computer to check.

My question - Is there a way for me to 'start fresh' somehow through the arcade itself and get my 3 controlers setup? Erase the controller mapping, but not lose the emulators/games that are on the card, then when I re-plug in the USB from the ipac, and things map correctly (or Id be happy to manually map, but everytime I manually map a controler, it only gives me the option to map 1 player, not all three after one another.).

Happy to provide as much additional info that would help.

Here are pictures of my setup. As far as I know, I have a series of buttons plugged into an ipac, which feeds through a usb cable into port 1 of the raspberry pie. https://imgur.com/gallery/k9hYc9m
