How to change resolutions of Mobile Java Games.

Rating: +38



Lets get to the point straight!

You have to open a *.jar file for example in WinRar and than open file “” from folder “META-INF”. Than write there this in the end:

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

First is original resolution of game and the second is the resolution of your phone.”

Detailed Info:

Open the jar(with winrar)

->open META-INF(directory)
->Open it to your desktop and open it with notepad)-add the two lines Nokia-MIDlet-Original-Display-Size: 176,208 (the original resolution of the game)

Nokia-MIDlet-Target-Display-Size: 352,416 (the resolution of you phone)

->Drag the edited back to your jar(in meta-inf directory)
->Close Winrar
->Send to phone

    I first use BlueFTP to extract all the items inside the jar file, then use Moby Explorer to edit the MANIFEST.MF file. After editing, use BlueFTP to compress it again.

    Good Luck raven!

    the reason u r having this invalid error is, u have extracted the whole jar file & zipped again after modification.
    but, u should not extract the whole file. rather open the jar file with winrar or similar. Then, go to meta-inf. There u will get the manifest file. drag the in ur desktop. then edit it following chaos’s rule. After that drag the edited manifest into the winrar window (from the place u dragged the manifest for the first time). Then save it.
    That should help u avoid the invalid error.

    Now, for the main problem. I did everything. But, still the game resolution didn change at all in mobile. I tried to change the resolution from 176×208 to 240×320. Nothing happened. Any help on this?

    Hi Chaos,
    Your site is cool. I tried to change the resolution of a java game, i did exactly what is written in your tutorial. But when i started to install it in my phone, it become an “invalid jar file!”. I hope u teach me more, about this topic. Thanks and more power to ur site!
