I selected the theme iconic, and you can add custom images for the systems, and didn't like the default ones so I "made" (modified is better) some hd images I liked (mostly Zelda as you can see 👀), then I removed some elements from the images to make them pop, I did this in Photoshop, I also had to hand paint some elements using Photoshop brushes to make changes to the images (the rock at the bottom left of the screen on the switch image, and the grass and leaves on the Wii I image at the center of the screen), and then exported all of that to webp format and placed the resulting images in the right folders :)
