Are your AGA directories games are in the 1st Level or 2nd ?
Is it because of the buffer running out ? (if yes, I'm going to fix that).
@With a "AGA" folder (containing games) in the middle, your games won't be displayed/sorted correctly in the list.
This is the reason why I don't scan the second directory. If something is found in the first one. I would have then to reorganize the titles... and I think it would be slow for a A500.
