I have created a prototype using 4.0 Beta and now my client wants it offline. I know it is JS API is unstable due to heavy development but I only need following AMDs.
require([
'esri/Map',
'esri/Basemap',
'esri/layers/ArcGISElevationLayer',
'esri/layers/ArcGISTiledMapServiceLayer',
'esri/views/View3D',
'dojo/domReady!'
])
I have downloaded init.js file but is not only file required. On line 23 this says:

load extra content from js.arcgis.com/4.0beta1/dojo
can I provide dojo release that is being shipped with current version of JS API? Where or how to download it (even by downloading file by file) so that I can run it in offline environment? Any way out? Any trick to make it work offline.
Any tip would be highly appreciated.
Thanks
