Better widesky for SF2 series

This is an extraction from a super vannila pack of WOX that we share in the small circle of Insky team. This time we update it to fit SF2 series.

it is just an light update for the excellent Widesky 1.0 from Cellisky

it has resolved the horizontal light band issue that has been around for quite a while

some old effects such as the twilight has been abandomed, using the original effect from TW instead. This has also improved the darkness at night.

This update has only been tested with SF2. We do not guarantee it would work the same way in earlier titles. Please use it on your own discretion.

Enjoy it, and feel free to report any problem.
