Go to D:\Program Files\GameHi_USA\globaldk\bin\options and edit this line, change the red numbers to your screen resolution
Code:
display [color="red"]1024 768[/color] 16
Keep in mind that the game window will shrink, but in-game windows wont, meaning that if your stat bar is 200x150 and your screensize is 1024x768, you change the screensize to 840x460 the stat bar will stay 200x150!
