Want to add more icons to my romlist

[Coffee_Pyramid]

I want to add more icons to my romlists for my games, such as beat'em ups and educational icons, as shown on the bottom of this picture: https://i.imgur.com/CHmZtMy.jpg
You can see the sports icon and text details are taken from the romlist from each system. What file do I need to modify to add more categories to these displays to show up?

Images go into the \attractmode\layouts\robospin\robospin\glogos folder and their names must match the "Category" field of the corresponding \attractmode\romlists\<emulator/system>.txt romlist.

I am able to change the icons by editing the romlists, but only to the ones that were preset with this image, like rpg1.png, puzzle1.png, shooter1.png, etc. but I can't make my own .png file to show up. Is there maybe another file thats only allowing the preset images to only show?
