I just noticed that at least First and Second Quest don't have the NES-style vertical scrolling anymore.
Feature Revert: Standard Quests no Longer have NES-Style Scrolling [576]
Uh oh, wait, do you mean that the "smooth scrolling" rule somehow got checked on them, or something else.
try the proposed quests.
Ignore 1st and 2nd.qst. They're no longer up to date, and will be replaced as soon as the proposed quests are thoroughly debugged.
