Thanks, Andy, you steered me in the right direction.
GPIO13 would not work at all, continuing to research that.
GPIO25, once pullup=GPIO25 was added, works.
I only have 1 limit switch setup, so I'm fully functional with the official image, Byte2Bot board, and my old Probotix motor driver setup. Attached are the .hal and .ini files that worked, and my config.txt
