To capture a bigger piece of the mobile games business, RealNetworks is courting game developers by offering to distribute, test and adapt their games for multiple mobile platforms.

The company is hoping to attract iPhone, mobile and PC game developers to its new "Federation of Studios" publishing system, based on the company's internal game development tools. It's announcing the program today.

Real would receive a bigger variety of games in return for handling the complexity of developing titles for multiple platforms. The company would also share revenues.

Real's internal tools, which it acquired in 2005 from a Finnish development studio, port games to more than 1,700 handsets. Real also distributes games to most major wireless carriers and direct to consumers.

But the doors aren't being thrown fully open. The company will select which game developers may participate in the program.

"We will review all comers,'' said Charles Harper, general manager of business development for Real's game unit. "We're going to be fairly selective anou who we choose."

Harper said it will take about five weeks to port, test and submit games to various mobile outlets.

The company isn't diclosing revenue share because terms will vary, he said.
