This newest update fixes a couple of bugs related to your handheld's battery while running PSPvista, as well as other bugs which caused images to load improperly.

# Creation of the rotation function of windows in 3D which is now 100% functional and serves as the office of Windows Vista with more features!
# The program will display "Low Battery" if the percentage of battery is less than 15%.

# The old bugs caused by loading images were eradicated for the most part.
