Hi. Love the work you've done on this theme and am currently using it. I do however use BigBox for PC, Switch, and some other unsupported consoles in your theme. I love the work and have tried fooling around with the xaml files, but without any proper extensive tutorials I think it is way over my head. I am however proficient in photoshop/Illustrator. I did do a quick mock up of a PC example.
If Interested I would be willing to do some more mock ups or the artwork for the missing consoles. I am currently working on PC, Switch, Wonderswan, WonderSwan + Color, 3DO, MSX, and Neo Geo Pocket + Color.
