C-style stdout/stderr will be supported soon and will print in the
browser console. About file access we don't believe it's a good idea to
provide a fake implementation of a filesystem on top of http requests.
You can actually use XMLHttpRequest to load the data you need. Textures
should be loaded using HTMLImageElement as the browser will
automatically handle decompression in such case.

You can take a look a the source code for the nontetris demo
(https://github.com/ddiproietto/nontetris) as it implements a possible
solution to load both text data and images from the server. Most
relevant code is here
https://github.com/ddiproietto/nontetris/blob/master/src/fileloader.h
