• Some unlicensed carts are badly made and can only take 3.3V rather than the standard 5V, and will be damaged and and potentially damage the console/dumping hardware, if provided with more than 3.3V. You should check what voltage the components of an unlicensed cart can take before using it, and if it requires 3.3V, making sure to set your dumper to the correct voltage, and not using the cart on a console (unless its modified to work with such carts).
