Only two things are changed:

1) The font - the more generic game font a lot of NES games use - has been replaced with the more iconic Kemco font seen in games such as Shadowgate and Deja Vu. It's baffling that font wasn't used in the first place; it's a nice font!

2) In the original game, most of the text windows are just plain, bland rectangles. The intro and ending sequences of the game use far more interesting looking window borders, so the border from the ending has been applied so that its used at all points in gameplay.

Those are the only changes made. Nothing major, just something that's a bit more visually exciting!
