CHANGING THE SCREEN RESOLUTION OF JAR APPLICATIONS & GAMES
Sometimes you download a game or software and notice that it doesn't fit your screen. Now, here's what you need to do.
You have to extract the items in the *.jar file using WinRar (for a computer) or X-plore (symbian phones) and then open “manifest.mf” from folder “META-INF”. Then write these two lines in the end:
(where the first line indicates the original resolution and the second line indicates your preferred new resolution, e.g for Nokia E65, it is 240x320 written as 240,320).
Then Save the manifest.mf back in the META-INF folder and zip your contents to jar format.
