			Runs done on the Japanese version of Contra can save a significant amount of time over runs done on the U.S. version. The Japanese version has a cut scene and a map scene which can both be skipped by pressing the start button. After skipping both stages, the next stage appears immediately. In the U.S. version, a mandatory transition screen that displays the stage number and score is shown before the next stage appears. There are 7 stage transitions with skippable cutscenes in the Japanese version. To convert the time, measure how much time was saved transitioning cutscenes in the Japanese version and subtract it from the amount of time spent watching mandatory stage transitions in the U.S. Version.
