SCI: handle given coordinate to draw() inside SJIS font support as if the horizontal part would be the center of the character, fixes not perfectly centered japanese text. I assume that PC98 ROM also handled it that way. The actual cause for those "bad" coordinates is GetLongest(), but that behaviour is definitely how sierra sci does it
