This application is probably not of use for the community but some official PS VITA developers.
I required it just for some tests, but it would be a waste of codelines not to share it, so here it is:
PS VITA Live Area preViewer outputs various information about a game, including it's style it uses on the PS VITA.
To use it, simply choose the root folder of a PS VITA game. Then check the style in the upper right of the program which it is ment to be displayed with and choose the correct tab. All else is self-explaining.
