Midway, like MBE is a stand alone program that doesn't need installing.
1) Now that you have it enabled--on your T720, go to Settings, Java Tools and select Java App Loader, it says to Insert Cable Now, so go ahead and do it. If successful you will get a messege on your phone saying "JAL Link is Active..."
2) Open Midway and go to the Settings, in the settings choose either Com port 3 or 4. You can find out which port you phone is on through the Control Panel in XP.
* Before we go further, you should know that to load up a game, you need two files, a Jad and a Jar file. To avoid potential errors, open the Jad file of the game you want to load and look for the MIDlet-Jar-URL: This should only have the name of the game you are trying to load, Not the url of a website in with it, then the name of the game, for example...
You may have this after downloading a game from the net...
MIDlet-Info-URL: Http//www.gotthisfrom thissite.com LunarTanks.jar
But the way it should look is just like this...
MIDlet-Jar-URL: LunarTanks.jar
I have noticed time and again errors when the url of the game hasn't been removed.
3) Click the Open Jad Icon, and browse to the game you want to upload, once it is opened you will get a rundown of the info of the game.
4)Click on the Send Jad Icon
5) On your T720, you will get a screen saying a File want to be added, click on the Download softkey and it is on its way! Once it recieves the file, it will automatically install it and if successful you can go to your games and play it to your hearts content!
A couple things to check if you get errors...
Check to be sure you have Midway set to the right Com port.
Make sure you did the above mentioned with the MIDlet-Jar-URL:
Make sure you have enough space! I have been able to install 7 small games, but only 2 larger games at any time, there is not a whole wack of space to fit all your games and apps, so load what you think you will play at any given time, now that you can change them as you want.
Use Google to find out if the game you are trying to load is indeed compatible with a T720! You can also find a T720 Emulator on Motorolas website called Motorola SDK v4.0 for J2ME after signing up with them.
Visit Howard Forums and use the search function, it is an amazing forum that I have found tons of info on, including links to free midis, wallpapers and games!
