Locate the following text lines: -
[FrontEnd]
EASplashWaitTime=3
WBSplashWaitTime=3
LaunchCode=0
and change the numbers in first 2 lines to whatever you wish, or 0 to disable both the splash screens
The last 3 lines of the file should read: -
fDamageMultiplier_Easy=1.2
fDamageMultiplier_Medium=2.0
fDamageMultiplier_Hard=3.0
Change them all to 0, if you wish to take less damage on being hit. You can also change them to any number you like for a desired effect. Save the file once for all. You don't need to do this cheat every time you play
