Hm. Nope. Whatever that "materials.cdb" file is, its not a "Constant Database" file. Found information on the CDB format here: https://www.unixuser.org/~euske/doc/cdbinternals/index.html The first 8 bytes are 4-byte binary integers followed by a bunch of 4-byte offsets into the file. This file starts with "BETH" and then lots of ASCII characters. So no idea what type of file we've got here.
