One of the few problems with having a phone with a nice big display is that many games do not display full screen. No problem! It's an easy fix that anyone can do and you'll be running full screen games on your phone in no time.

Note: This will work about 95% of the time on S60 3rd edition phone models. I have not tested it on other models but feel free. This will not work on phones with a landscape screen (E series). This will work with any MIDlet by the way, not just games.

Guide

1. Using an archiver such as WinRAR, open the jar file.

2. Once you have opened the jar, you will see a folder called 'META-INF'. Open this folder.

3. In the META-INF folder there will be one file called 'MANIFEST.MF'. Drag this file onto your desktop and open it in notepad.

4. Now you must know 2 things to edit the file. First, you must know the original resolution of the game. Ususally this information can be found on the author's website. Second, you must know the resolution of your screen. Then type the following two lines at the end of the text in the MANIFEST.MF file:

QUOTE
Nokia-MIDlet-Original-Display-Size: www,xxx
Nokia-MIDlet-Target-Display-Size: yyy,zzz


In the example above 'www,xxx' represents the original resolution of the game. 'yyy,zzz' represents the resolution of your phone's display.

In the picture example below, the original game resolution is 176x208 and the target resolution of my screen (N80) is 352x416.

5. Now save the changes in the MANIFEST.MF file and drag it back into the META-INF folder in your jar file to overwrite the old one.

6. That's it! Now install the jar to your phone and enjoy your full screen game...

:good:


EDIT: Btw, full credit goes to skopi (from another forum) for posting this info. :clap: I just tried to make it a little easier for everyone by posting my own guide including pics.

Yes, it definately affects the speed of some games, especially on the slow processor of our poor N80s... :(

Best to close all other apps before playing relatively graphics-heavy games. At least then there's a chance! ;)

I have just read the whole guide. The only problem that I have is the original screen resolution. I'am trying to find the screen resolution on the websites of the authors of some games (like townsmen) and i cannot seem to find the original screen resolution of those games. Is there any compendium or list of game screen resolutions that is already existing?

Just give it a try. You can guess pretty accurately in most cases.

For example, if you have an N80 (352x416) and you open a game that only takes up a tiny corner of the screen, then it's probably 176x220. If it takes up a larger portion of the screen but not all, then it's probably 240x320. Etc...

Cool this helps me as I'm used to how Sony Ericsson's can resize an java ap, I tried to find an option in phone on my 5500, but of course found nothing, so its nice to know there is a way to do this, thanks.

*EDIT*
Well I've just tried this out and it works great for my 5500, I did use 7-Zip though, cause its free, but it still worked fine, again thanks for the thread.
