This is a PAL exclusive as far as I can tell.  We aren't tracking PAL games for PS4 or Xbox One quite yet.  I'll add this when we do include those.

Emailing is the best option at this point.  I've added you as a beta user for a user editing feature we are working on.  That will be the best option in the future, but it isn't live for everyone yet.

That game image has been changed now.

You can add 1st party accessories and controllers to your collections.  We do not track 3rd party controllers or accessories though.  They are generally not very valuable and there are so many of them from tons of different companies.

Thanks for spreading the word.  We are working to add more and more PAL coverage.  The more users we get to those consoles, the faster we can add them because it helps us see how popular they are with users.

Can you post a photo of the official controller you are referring to?

We have the expansion pack already.

How is that version determined from the standard versions?  I thought all original Genesis units had that "High Definition Graphics" wording on them.

Were joycon controllers ever sold individually?  I've only seen them sold in pairs.
