Nesoid
NES emulator for Android phones
This project is based on sources, published by original Nesoid developer, who in turn used code of GPFCE, forked from FCEUltra, currently incarnation of which is known as FCEUX. Help and suggestions are welcome.
This project has been abandoned in favor of the RetroArch, another awesome free software emulator (which has much better NES support and is more actively developed): http://www.libretro.com/.
