nfs_carbon.jpg_320_320_0_9223372036854775000_0_1_0On the internet you can find plenty of Java games that can be downloaded on to your cell phone. Even though these games install properly on your phone, you may encounter several problems while playing the game. One of the most common problems is related to the display screen size of your cell phone. The game may appear very small or big as compared to the display screen. In some cases, the game is displayed at one corner of the screen.


  1. Any Java game (.jar or .jad)
  2. Install Winrar on your computer. Winrar is a file compression and extraction tool

Here’s what you can do to rectify this problem:

  1. The first thing you need to know is the original resolution of the game that you have downloaded. This can be done by visiting the game developer website and checking the requirement list of the game.
  2. Find out the screen resolution of your cell phone. This can be done by reading the user manual or technical specification of your cell phone online.
  3. Open the Java game file by making use of Winrar.
  4. Inside Winrar, you will see a folder named ‘META-INF’ and inside it you will see a file named ‘MANIFEST.MF’. Drag this file out to any location on your computer that is easily accessible to you (for example: desktop).
  5. Open the MANIFEST.MF file by using a Notepad. This can be done by double-clicking on the file and then choose the Notepad application from a list of programs available.
  6. Once the file is open in Notepad, add the following strings below the last row:
    Nokia-MIDlet-Original-Display-Size: xxx,xxx

    Nokia-MIDlet-Target-Display-Size: xxx,xxx

  7. Now, you need to edit the ‘xxx,xxx’ as per your phone’s requirement.
    Original Display Size is the original display size of the game (for example 176 x 208).
    Target Display Size is the display size of your phone (for example 320×240).
  8. Save the file by retaining the same file: MANIFEST.MF
  9. Drag this edited MANIFEST.MF file into META-INF folder by means of Winrar. A dialog box will prompt you to replace the older file with the new one. Click on OK to confirm it.
  10. Now you can install the game on your cell phone and see the game occupy the full-screen of your cell phone. This way you can play and enjoy all your favorite Java games on your cell phone without any display problem.
