HalfNES is an open-source emulator for the Nintendo Entertainment System, written in Java. Currently, it will only run as a standalone Java SE application.

Default Controls:
D-Pad: Arrow Keys
B Button: Z
A Button: X
Select: Right Shift
Start: Enter

Note on joystick support:
HalfNES must be launched using the "run.bat" file for joysticks to work! The lib folder must also be in the same location as halfnes.jar is. The first detected gamepad will be used as Controller 1, and the second will be Controller 2. Currently the buttons used are not configurable.
