"The Nintendo Donkey Kong boards are old and their various electronic parts are aging at different rates. As those components near failure, the potenfial for visual arfifacts increases. This means there is no way to compare different Donkey Kong boards as their component failures most likely are in different parts. This
includes the power supplies that power the Donkey Kong boards," Zyda wrote. As those power supplies age, we have no way of measuring how that aging will impact the Donkey Kong boards operafions
and visual display. As such, there may not be any way to compare recordings from the same board
done at different fimes. In my opinion component aging could produce the anomalies at issue."
