FreeINESs - Free 8bit Console Emulator for Android

This app runs games written for Famicom, DiskSystem, and VS System gaming consoles. It also emulates addons, such as tilt sensors, light guns, vibration packs, printers, and more. The emulation is specifically opimized for Android devices. It lets you save game progress at any moment, or even rewind gameplay back in time. You can exchange saved game states with other users, or play together by using the network play. This app supports AndroidTV, GoogleTV, and a variety of gamepads, including Xperia Play, Moga, iCade, Sixaxis, Nyko, and others.

Disclaimer: Since all the Famicom software is written to run in the 4:3 NTSC TV resolution, FreeINESs will display it in the original resolution, with black bars at the sides of a 16:9 screen. If desired, you can make the image fill the entire screen via the "Settings | Video | Stretch Video" option.
