Hi, no I haven't - didn't think that would work, but maybe it's worth a try.
I was thinking though that once a project is converted to an mxf or amxd then unless there's some clever intercepting going on (is that even possible??) then the files won't exist on the filesystem, just as a resource in the file..
Edit: I've currently resorted to putting the contents I can in a dict and accessing that from C.
Yes everything is bundled and i think there's no absolute filesystem path to the resources but there's something like a project intern working directory at runtime I guess. And C can open files with a relative path, too.
