@susahamat:
First of all, thank you -- the widescreen hack works in general, however there is one major annoyance: whenever the game does a "fade out", i.e. when starting and ending battle, the screen goes black for a second, and during pep ultimates, the screen has white fade outs multiple times... those were supposed to be fullscreen, but now with your hack, they are aligned to the left side of the screen and fill only the old 2560x1440 area, instead of being a fullscreen effect.
This means that ~2/3rds of the screen regularly black out or white out a number of times during combat, and upon area changes... this is insanely annoying and immersion-killing, so the big 1.000.000 dollar question:
Can this be fixed?
Apparently this is also tied in to the splash screen and menus being aligned to the left side instead of centered/fullscreen, even the crafting result popup (Success/Perfection) is off-center, and second screen shoes the white fade outs while crafting also with the same visual bug.
