It’s sheer eye candy. A modder who goes by Hatrix gives the Nintendo DS a touch of retro NES flavor. An amazing feat of design, Hatrix took apart his entire DS, sanded off the paint, rubbed it down with a brasso, and carefully integrated the NES controller face logo.
“I went for the style of the original DS with the black middle, but didn’t quite get there.. still it looks pretty good. I cut the button holes in the top of the lid and stuck the NES buttons and Start and Select buttons through, but the Directional Pad I simply glued on with super glue.”
