Mobile games with Banner Ads

- we dont need the source code or copy rights. we just need game with Banner Ad

Its better if you take the source code of the game too so that in future, if you get any problem in the game, you could always hire a programmer to modify the game cheaper than it would take for making a game from scratch.

- for the same game we need to specify different url for different clients

Yes thats possible for example, create a website and in its database, enter all your clients and the url's they should be directed too. And when you sell the game, the id of the client must be registered (hard-coded) in the game. So when the ad is to be displayed, the mobile supplies the id of the customer to the website and retreive the link of the ad and display the link. I know there are other methods, but this one sounds hassle free.

- vendor should give us provision to pack(eg. jar etc.) the game(eg. midlet etc.) with

Yes, again this is realistic and possible

specified url to fetch Banner Ad (eg. jpg etc.)

yes. with the website-fetch method I describe earlier, this can be done. Though of course carrier charges for the use of internet would apply.

- vendor should give us provision to pack a default Banner Ad (eg jpg etc.) with the game

This would be most hassle free, I mean if this is possible for you because you might be selling 1000 games, you would have to pack the ads to the game, but using this method, no carrier charges for internet usage. I guess once the game is purchased and ready for selling, you could hire a data-entry operator and give the task to add banner images to him (of course, the game should have the provision but thats possible in terms of programming)

- if the mobile has no wap, the game should display the default Banner Ad

Yes, internet connection can be detected via j2me (programming) again this is realistic

- Also I need to know which technology games (eg. j2me/windows mobile) to choose for most supported mobiles in market

The most supported technology in my knowledge is J2ME since the majority of the devices support this technology, I mean, even windows mobile support it. But if a game working for Windows mobile is created, it wont run on cells having android os or symbion os. J2ME has become a standard technology. BREW is another network where they would market your game (you got to register the game) but again it is only supported on cells supporting BREW. Honestly, in my openion, J2ME is the best option.

Also please give us list of sites where we can purchase games with minor customisation like above.

I guess you must turn your attention in this regard to freelance websites like http://www.guru.com http://www.getafreelancer.com and hire a programmer for the project to create a game like this, for example, he would charge $20/game etc (depending on how you bargain)

For porting problem, thats the same thing I told before, I mean games for Windows Mobile have to be ported to be able to work at Symbion, Android etc. Thats the whole point of why you should use JAVA (J2me) as they say "Write once, run everywhere"

And finally for licensing, if you are making a game for iphone or BREW mobiles, you got to get a license but for games in JAVA, you dont need any lisence you can create/distribute the games free if you like.

Hope that answers all your questions
