After installing Dragonbreaker UI, I noticed that everything but the hero menu looked to properly scale with my ultrawide display.

Seeing that Enderal Ultrawide UI doesn't have this issue with its hero menu, I dug into the swf files and adjusted the header display and framing params within Dragonbreaker's hero menu to match. The result is what you see below:



You can easily do this for any hero menu by doing the following:

• Using JPEXS, open 00e_heromenu.swf
• change headers to the following
  0,0 => 34400, 14400 twips
0,0 => 1270,270 pixels
• Go to frames --> frame 1 -> PlaceObject2
• Edit and change the following under matrix:
  translateX : SB[nTranslateBits] = 4399
translateY : SB[nTranslateBits] = 2
nTranslateBits : UB[5] = 14
