I'm author of this theme. The theme is not finished yet but I will be happy to port it myself when it's closer to completion. For the most part it will only require some folder name changes (e.g FBA is already supported, it's just recalbox is expecting a different folder name).
So far it supports 42 different systems and more are being added, it will just take a little time as I need to draw backgrounds, logos and icons for each system.
