HOW2 - Change the Resolution of Java Games

[bornagaibiker]

Hi
This should help a lot of people who are wanting games which are only out on bigger or smaller sized screens than the handset there using.

1. Open your game *.jar file on your computer with either WinRar or WinAce or any other good compression program.

2. Go to the META-INF folder and by using notepad, open the file called manifest.mf

3. Scroll to the end of the file and add:

Nokia-MIDlet-Original-Display-Size: (the original size)
Nokia-MIDlet-Target-Display-Size: (what size your display is)

Example:
Nokia-MIDlet-Original-Display-Size: 352,416
Nokia-MIDlet-Target-Display-Size: 240,320

4. Save your changes. Depending on which program you use you may need to "re-zip" the entire *.Jar. Install to your phone and ENJOY!

okay, i've tried this but every time it says its an invalid .jar file..and wont install...

any chance someone has edited Midnight Pool to work with the e60 resolution? or perhaps give me another idea? i have a mac and a PC, so i could do it on either platform, but prefer mac...

Bro...how u zip back the .jar?

[phoenixraj]

for you all !
U need to associate your .jar file to WinRAR.
Here is how u do it on WinRar 3.51
Option->Settings->Integration Tab-> Check on JAR checkbox.->Click ok.
The association is done and your jar fils will shown as rar file.
Now open the Jar file with winrar and edit the manifest.mf file.
NOTE: This will work from Small to BiG and may not work that correctly from big resoluotion to small resolution.
enjoy.
