to stop the crash on RuF Spoiler: Only if your ready to know how. You will need to know some basics of RuF but the main fix is to search in your computer for the already installed application (REGEDIT) then on that for HKEY_CURRENT_USER under that look for SOFTWARE then look for the NIMONIX folder then look for your game provider for USA RumbleFighter for Japan RumbleFighter_JP and for this one i would not be sure click on the folder then click on the wwhite then create a DWord 32bit then after you have done that name it exactly like this Windowed then click on the value and hit enter then type 1 and confirm do not put the game in full screen hope this helped if this helped like it up!
