Higher Speed/Acceleration:

At the initial copyright screen, press every single button at the same time on both controllers to make a combination of Up + Down + Left + Right + A + B + Select + Start in total. You can press the opposite D-Pad directions on the different pads. For example press Up + Right + A + B + Select + Start on the first controller and Down + Left on the second controller. A sound will confirm correct code entry. Instead of 192 mph, you'll be able to reach 201 mph and the faster acceleration. (If using just one NES controller, you must use a specially-modified one; normal ones don't allow pressing all D-Pad buttons at once.)

Skip Scene:

In the European version, an ability was added to skip more info and animation screens than the normal US version's "Skip Racer Info" code. Just press A + B at the the title screen.
