Its ok. This thread is specifically for the Adv guide, such as something missing or there is an error, etc. Regular questions can still go into the VGDB section and it is better for them to be in there for visibility.
I answered your question (I hope) in the thread you made there.
In general, the name should match the name on GameFAQs
for that specific release but we have no rule for releases that are not there. Other than you can get the name from some other site, which is to then open it up to Mobygames or some other wiki. Or as I like to think of it "I get to name a thing" instead.
For alt-name, it is primarily for searching, as our search will look into there too. As such, actual text formatting is not that important, as long as the terms are present. You can put in Disney and/or Pixar into there if you want, english name, some other language name (for that release) or common translation (as is the case for some Japanese exclusive games based on anime that was released in other areas outside of Japan. Just whatever you can think that would help someone find a thing if they didn't know the language.
EDIT: Arcade section done for now. Was going to work on the next section (Sega Genesis/Mega Drive), however there is a change required in the forum before it can be started. So if you saw that topic for a short time, that is why it was removed. I will take a break from working on new sections in there until that has been resolved.
