I suppose this means undroidwish should be recompiled when there is need for a change to the sdl configuration.

Looking in the directory tree of the source code, I see that the assets/app dir is missing. So I created it and populated it as per the instructions, but `build-undroidwish-linux64.sh` does not copy the contents of it to the build dir. So here is an one line monkey-copy patch that copies the dir and the files, and make it work:

>   cp -rp assets

Thanks!
