Changing screen resolution of Java games

Ever wondered how to change the screen resolution of the java games to suit for your Nokia phone. Here I am going to talk about the ways of changing the screen resolution size of the java games.

The .jar files are nothing but just the archived files so you can use winrar to open the jar file in your PC. The jar files consist of a special folder meta-inf which consists of a file manifest.mf with the few important information about your java games.

What you have to do is open this manifest.mf in a text editor and add the following lines at the end of the file.

Nokia-MIDlet-Original-Display-Size: xxx,yyy
Nokia-MIDlet-Target-Display-Size: zzz,www
Example:
Nokia-MIDlet-Original-Display-Size: 176,208
Nokia-MIDlet-Target-Display-Size: 240,320

First one is the original resolution of the game and second one is the target size of the game.



Finally save the manifest.mf in your jar file and there you go.

This might look a bit harder and confusing for the new people so there are the java resizing softwares out there to change the screen resolution of the .jar files. One of them is a software JarResize. You can google for this software and use this software to easily change the screen resolution of the jar file for your Nokia phones.
