[How to show a category in the main Big Box list?]

Yes Retro808 is correct.  But you can still accomplish what you are trying by setting main view to platform category.  Then you have a couple options.  You can set it up to have only one menu before you get to your games.  To do this just created an auto generated play list for each system you want to show up on the main list.  You can also set it up where you have categories on the first page and then they open to another list of categories IE  Arcade/2 player/ 

If you use Platform list you can use what ever folder structure you want you set what category, platform, or playlist in the edit options under the parent tab.  

In the example I added a pinball category that shows on the main screen You could also do this with a play list.

In Bigbox you need to go into the settings screen and go to Options/Views/Default Startup View and Set it to Platform Category. Hope this helps.
