Is it possible for RetroArch to somehow expand on recognized file names?
FBA creates a database file containing information specifically for this purpose. The file information inside the file looks something like:
<game name="sfiii3">
<description>Street Fighter III 3rd Strike: Fight for the Future</description>
<cloneof></cloneof>
<manufacturer>Capcom</manufacturer>
<year>1999</year>
<genre>Fighter / Versus</genre>
</game>
If something like this could be implemented(maybe it already is?), it would make navigating rom files much more convenient.
