Hey is it possible to run this game on a windowed mode?

Hi,

sure it is. Open the XIII.ini in X:\PATH\TO\XIII\System\XIII.ini in a text editor.

Find the block of text looking like the following one and edit the bolded values for enabling window mode + resizing.

[WinDrv.WindowsClient]
WindowedViewportX=800
WindowedViewportY=600
FullscreenViewportX=1280
FullscreenViewportY=720
TextureDetail=High
SkinDetail=High
Brightness=0.500000
Contrast=0.500000
Gamma=1.000000
MipFactor=1.000000
UseJoystick=False
CaptureMouse=True
StartupFullscreen=False
ScreenFlashes=True
NoLighting=False
DeadZoneXYZ=True
DeadZoneRUV=True
InvertVertical=False
ScaleXYZ=1000.000000
ScaleRUV=1000.000000
MinDesiredFrameRate=60.000000
Decals=True
NoDynamicLights=False
SkinDetail=High
TextureDetail=High
NoFractalAnim=False
...

Kind Regards
