You could check the test cases of the format's self test.
If these are the same formats, they usually also have the same self
tests (exception would be a test which would fail because one
implementation supports a smaller maximum password length.
(For dynamic_10NN, the test cases are in the config file dynamic.conf.)
BTW: Some formats which currently collide with other formats could get a
changed canonical representation. At least those which av an individual
conversion script or routine:
$ ls -l *2john*
These formats could still support the old format. But the sequence of
format registration might need to be changed in case they grab hashes
which are the canonical form of another format.
But that is certainly stuff to be checked after the contest.
