The latest version for the NES emulator for the iPhone has been released addressing some bugs and adding some new features. The NES app from developer nervegas allows NES games to be played on the iPhone.

This version (0.99.07) fixed a rare bug that causes the controller to freeze. This was addressed in v0.99.06, and the fix caused incompatibility with save games from previous builds. Here's the changelog for v0.99.07:

* Added alert with instructions when no ROMs are detected
* Added alert for invalid game genie codes; don't save
