Start with the provided Input_Display.lua script, especially the arithmetic failure reported at line 111, and inspect its output in the Lua Console while running the N64 repro with the ARES and Mupen cores. Done means the script acknowledges connected controllers for the tested setup and no longer reports the nil-value exception during inputs.
