Installing Games

Posted: 13:44 04 Oct 04 #1
I have downloaded some great looking games, but can't seem to install them, as there is no jar. file when I unzip - just a large amount of different files.

Is there an easy way of installing the game? I have a DKU-2 cable, and am using pc suite.

Please help the uninitiated!

OK. A lot of people have had this problem so here goes.

The explanation:

A java game is made up of two parts, a JAD and a JAR. The JAD file is just a plain ASCII text file that contains various descriptions. The JAR file is a compressed file that contains the compiled code, graphics, sprites and sounds which can be opened in WinZip.

Often the two parts, JAD and JAR are zipped into an archive, for example. Opening in WinZip would only show two files, game.jar and game.jad for examlpe. If this is the case the file can be unzipped and installed as explained below.

Sometimes however you can only download the JAR part which has either been renamed to or sometimes to just If you open the file in WinZip and find it contains a lot of files, eg .png, .class, .midi, etc then it is actually the JAR file, but wrongly named.

How to fix and create the .JAD:

If you open any file and can see lots of .png, .class, .midi, etc then rename this file to game.jar. (You can use any name GAME.JAR is just an examlpe) To be able to install this file you will need to create the .jad header file. My personal favourite for this is a program called JAD Wizard v1.1 which is freely downloadable from the net. When you run JAD Wizard a mobile phone image will appear on your desktop. Just drag and drop the .JAR file onto it and it will create the .JAD file in the same directory as your .JAR file.

How to install:

You can now install the game using Nokia Application Installer (Note it will be installed in the Applicatins folder) or you can drag the .JAD file to the Games directory using MobiMB 2.2 (it will be installed in the Games folder)

Happy Game installing

Right i'm really struggling to manage the re-naming of the files. Is it the unzipped folder that we have to change the name of, or each individual file in the folder? When I've renamed the unzipped folder and dragged it into 'JADMaker1.10' I get the following message:-

"Run-time error '53': File not found"

Is it possible I can e-mail the downloaded unzipped file to someone that knows what they are doing to check its possible with the game I've got???

Thanks, Tim.

Not as far as I know, they should have sound. You might need to activate it, on the game or in the phone settings.

Hi Matt,

.Rar files are compressed files, sort of like a .zip file. You'll need to use a program like WinRar ( to extract the files before you can transfer them to the phone.

Hey, I have the same problem. I just spent 1 hour to download programs and try to install games which is a lot even for this kind of thing. I downloaded the Nokia Application Installer but it does not see the .jad file, only .jar. The MobiMB 2.2 says there is a problem with adding a new connection. The drive letter already exists. I have a question:

I'd really appreciate some here, thx!!!!

You don't miss anything wihtout jad.

Here's y problem: In phone memory there is ~1,6MB of space for games and programs. That space aint sufficient for me. Is there any way to increace the space or install stuff on MMC?

I have a MAC too (Powerbook G4, 1.5 MHZ with integrated bluetooth adapter). Actually I can browse through my Nokia 6230 and upload/delete/download easily files (mp3, jpg, mid, jar) into the different folder of my Nokia except into the games directory. The problem I have is that when I upload the games in "rar" or "jar" format, Nokia considers them as "unknown file format". Maybe I should unzip them before uploading. I will try and let you know.
I didn't try to use Isync to sync contacts with my Nokia 6230 but with my previous bluetooth Siemens S55 phone it worked fine.

Hello, I cannot seem to install any game in my phone. Whenever I try installing a game and test it, I get the same error in spanish: Formato archivo no admitido (it is a spanish phone), which translates roughly to : file format not admitted.

Please help. What can I do?

P.D. I transfer the files via Bluetooth.

Thank you very much.
