Having settings for each game in more than one file is redundant.
Now, region-free INIs are now only for settings, and region-specific
INIs are only for AR codes and patches. Exceptions are made for
titles that share the first three characters of their IDs with
unrelated titles (mostly unlicensed titles and Triforce titles).
He claims they don't work on that revision either, but from a quick
Google they (most of them?) seem to be intended for it, so keep them in
case they're useful for anyone.
