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!:D
Thnx man but it doesnt work
Nokia-MIDlet-Target-Display-Size: (what size your display is)

ok for the people who havent got it working, try it like this:
EXAMPLE
Manifest-Version: 1.0
MicroEdition-Configuration: CLDC-1.0
MIDlet-Name: X-buggy 3d-Zub
Created-By: 1.4.2_08 (Sun Microsystems Inc.)
MIDlet-Vendor: JOYES
MIDlet-1: X-buggy 3d, Racing.png, Racing
MIDlet-Version: 1.0
MicroEdition-Profile: MIDP-2.0
MIDlet-Original-Display-Size: 176,208
MIDlet-Target-Display-Size: 352,416
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...

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.
thnx bro!!!!!!!!!!!!!!!!!!!!!!!!!

Hey Guys,
I don't think this trick works with changing resolutions from big screens to smaller ones. I have test this trick on "The Sims 2" for Nokia N80, which has a 352 by 416 resolution and changing it to 240 by 320 but it keeps saying "Invalid Jar". Tested it with 176 by 208 resolution games to 240 by 320 resolution for Nokia N73 and it worked fine.
Do you have any idea how this thing could work with bigger resolutions and changin it to smaller ones?
Thanks,
Doms
