These mapfiles are available for your personal use. They are mostly based on priw8's eclfiles repo.
The recommended files to use are:
any.anmmfor ANMany.stdmfor STD
If you mess around a lot with decompilation and hate writing the path to this directory, you can tell truth to use these files by default during decompilation by pointing TRUTH_MAPFILE_PATH to this directory. (the resulting scripts will contain an absolute path reference to this directory, so don't do this for things you're checking into VCS!)
