Over the course of some years I've been creating high-def icons based on real images of video gaming consoles so my collection doesn't look so plain. I've uploaded the icons (PNG & ICO) so others might make use of them. Most of them are 512x512 or 256x256. There are a total of 250 systems (500 files).
Here ya go.
