The portaudio-go dependency requires PortAudio on your system:
To build portaudio-go, you must first have the PortAudio development headers and libraries installed. Some systems provide a package for this; e.g., on Ubuntu you would want to run apt-get install portaudio19-dev. On other systems you might have to install from source.
On Mac, you can use homebrew:
brew install portaudio
go getcommand will automatically fetch the dependencies listed above, compile the binary and place it in your
go get github.com/fogleman/nes
If no arguments are specified, the program will look for rom files in the current working directory.
If a directory is specified, the program will look for rom files in that directory.
If a file is specified, the program will run that rom.
For 1 & 2, the program will display a menu screen to select which rom to play. The thumbnails are downloaded from an online database keyed by the md5 sum of the rom file.
Joysticks are supported, although the button mapping is currently hard-coded. Keyboard controls are indicated below.
