MMI Software Tools Public Domain Version

The extract_it option should work fine in max 4.2.11.
It is mostly running the :extract command which is similar to the old magic one.

There is no reasons to compile max 4.3.16 for extraction.

As for other ways to extract RC's, you can write an extractor yourself in tcl using the various api's. Otherwise, use :extract which generates an .ext file.

Hope this helps,
