How To Change Java Applications, Games Resolution On Your Nokia Mobile?

In my previous post you have seen Emergency Calls From Your Mobile.In this post I will discuss about How To Change Java Applications, Games Resolution On Your Nokia Mobile?

Have you ever come across the problems with screen resolution on your mobile? Like when you tried to install a Java game or application and finds that the resolution is too small or too big for your phone. If you have problems like this, then you are just like me. Sometimes, I have to squint my eyes just to play the game as it is too small on my phone or its too big. So here is the solution for the above problems.


You can actually change the resolution of the Java Games for the Nokia phones very easily.

You should be using WinRAR for this. You can download an evaluation copy of WinRAR from
Using WinRAR, open the Java file. The Java file has a file extension .jar.

There should be a folder called META-INF. Open that folder.
Inside that folder, there is a file called MANIFEST.MF. Drag and drop the MANIFEST.MF to your Desktop

Open it using Notepad and at the end of the file, add the following two lines to the MANIFEST.MF file.

Nokia-MIDlet-Original-Display-Size: 176,208
Nokia-MIDlet-Target-Display-Size: 352,416

Now save the file. The drag the file back to the .jar file folder META-INF using WinRAR.

Install the JAR file to your phone.

NOTE: For your mobile what is the xxx,xxx (176, 208 and 352.416) in the Nokia-MIDlet-Original-Display-Size & Nokia-MIDlet-Target-Display-Size? It is the screen resolution.

Nokia-MIDlet-Original-Display-Size: 176,208
Nokia-MIDlet-Target-Display-Size: 352,416

The above shows that the original game resolution is 176×208 and the new target resolution is 352×416 i.e. for N80. The Original Display Size is the actual resolution of the game. The Target Display Size is the resolution you want the game to be displayed at on your phone, for example 352 ,416 is the resolution of the Nokia N80. For Nokia 3110c 128,160 is the Target-Display-Size.Please be aware that the resolution of a game can be resized larger but not smaller.

@ RTB we can not change the size or compress the jar file. That is not possible. Most of the jar applications are very vrey lower in size (say less than 500kb).So no need to compress it again.
