Theme system ‘auto’ categories.

[thinlysliceddan]

Hi there, I was hoping someone might be able to help me out here.
I’ve been making a new build with a pi4 and using recalbox 9.2.
I think I would comfortably fall into the ‘beginner’ category, so thank you in andvance for your patience. I have found the community here super helpful so far.
I’ve managed to get everything up and running and working fine, however
I noticed that quite a lot of the themes I’ve installed (pixel, hyper wall etc) have categories in the systems folder like “auto-arcade”, “auto-fighting games”, “auto-strategy” etc.

I’m not sure how to make these categories active and populate them with games. Would someone be able to help me?

Many thanks !
