This is a node-webkit wrapper for the great js99er TI-99/4A emulator by Rasmus Moustgaard.
Currently there are no binary packages available. In the meantime you can run the application from the 'app/' directory by running:
nw .
(Assuming, that node-webkit's nw is available in your PATH).
Optionally a RPK module filename can be specified as command-line parameter, eg.:
nw . ~/modules/munchman.rpk
