I've tried to find this information but cannot find anything. I have two questions:
1) How do you label the entry in the romlist (MAME, for example) so that a theme that is looking for this information will read it? It looks like the very last item in any entry in the romlist is defined as "rating", but no matter what I try in that spot (numeric, initial letters of the ratings, full text), my layout (Arcade Bliss Information Overload Edition) doesn't read the info (It is supposed to, I think).
2) Is there an "extras" file that has all of this information (similar to catver.ini) that I can point the MAME cfg file to read when building the romlist?
Thanks for any help you can offer.
