Description

— Product under development —

This is a full-color printed custom motherboard for the games Pokémon Red, Pokémon Blue and Pokémon Yellow for Game Boy. Select the version matching your original game when placing your order.

You can use it to customize your original cartridge, whose battery has long since died or whose original PCB has become damaged or corroded.

Additionally, as you can see in the photos, this new circuit will give your Pokémon cartridge an incredible new look. Pair it with a transparent Game Boy or Game Boy Color shell to show off the artwork.

FEATURES

  • New full-color printed motherboard for Pokémon Red, Blue and Yellow.
  • Compatible with original Nintendo MBC3 and MBC5 donor cartridges.
  • Replace the battery without soldering whenever it needs replacing.
  • Compatible with GBFlash, allowing you to back up your save before the transplant and restore it afterwards.

  • 1x Full-color printed custom motherboard.
  • 2x 10K 0603 resistors (1 required).
  • 2x 33pF 0603 capacitors (1 required).

(1) Remember to purchase the shell for the motherboard. You can use either a Game Boy or Game Boy Color shell, as both are fully compatible.
