The upcoming release of Sony Ericsson's Android-powered Xperia Play, also known as the "PlayStation Phone" has spurred Google into removing a PSOne emulator from the Android Market.
Its author, who goes by the name "zodttd" says that his app, PSX4Droid was removed without warning and given a "Content Policy Violation." He suspects that the release of Sony's new phone may have spurred the company into action.
Another PSOne emulator, FPSE, remains available on the marketplace.
