Hi there. My brother (Codyroo) and I have been researching UWNH runs extensively and we can confirm that the text speed difference between JP and NA versions is too significant to be combined. Mainly due to the fact that the JP version doesn't even scroll text at a set speed; but instead, decides to display the text instantly without a scrolling animation. This will result in a major time difference between JP and NA runs.

In addition to that, the player can navigate the menus at a much higher speed. I'm not sure why, but the NA version appears to have built-in delays in-between menu actions. I will work on providing exact time differences between the version and I will post that data in a new thread.
