Neptune Game Boy Shell

Retro Modding
| /

This marbled DMG shell is a first of its kind, and due to how the plastic is cast to achieve this marbling effect, every Neptune shell has its own unique pattern.

The Neptune name has been chosen by the retro modding community during the Instagram "Space vs Ocean" contest held on January 2021! 

Our unique, in-house, Game Boy shells are cast using proprietary, high-precision tooling to ensure a final product that's as close to genuine shells as possible. While low-end aftermarket alternatives may deliver variable results, our shells have been carefully cast to reproduce the style and feeling of the original hardware. With over 25 different color options, you can give your old console a vibrant, brand new look. If you're looking for trimmed DMG shells, these are available here.


  • Durable ABS (acrylonitrile butadiene styrene) material from Japan 
  • Printed A, B, Start, and Select text
  • Manufactured for a perfect fit with the DMG PCB
  • Machine cast with a lightly textured finish to reproduce the feel of the original shells
  • High-quality replacement parts with an accurate fit


    These DMG shells are also available in over 25 different colors, including airy pastels, clear neons, reproductions of Nintendo's original hardware colors and color-changing shells.


    • 1 x DMG housing with matching battery door
    • 1 x Extension (link) port cover
    • 1 x Set of brand new screws 


    • Battery contacts and metal shield not included
    • Colors may vary from what you see on your display
    • This is an aftermarket product and may not feel identical to its genuine counterpart

    Great shell replacement

    A great replacement shell. The material feels solid and not cheap once everything is together, and the cast is excellent. Love the colour marbling, too!


    I really liked how it turned out amazing colors but my main issues with it was when i was installing the battery contacts a small piece of the shell was blocking it so i had to remove it.
