I have found a really old thread from 2011 that suggest some sort of tool for that, but all the links there are broken already... Was unable to find anything else, so I thought I might ask here: how do I decode/encode res files (namely, Amber client's audio files for custom alerts). Is there any easy way for that?
If you point to a git repo of such a tool, someone else might be willing to compile it. I also have my own code to unpack and repack res files which I could turn into a separate tool if necessary.
