They also sell other mod parts, such as aluminum buttons, new screens, rechargeable batteries, USB-C charging boards, and much more. Aluminum shells for either Color or Advance run for $69.00 USD, and come in a variety of colors (anodization) including gold, silver (clear anodization), red, blue, and teal. They also come in a “solid brass” variant, which seems to be a “shinier” gold.
Unfortunately, at the time of this post the GBC shells are sold out, with a note saying they’re being “redesigned.”
We are currently redesigning and prototyping new shells. ETA is June.Boxy Pixel
I hope there’s as few (outward) changes from the official design as possible, personally! Their homegrown hingeless SP design is neat, but it’s hard to beat the people at Nintendo.
