In order to bring the Game Boy™ and Game Boy Color™ experiences to Nintendo Switch™ via Nintendo Switch Online, NERD developed a brand-new in-house emulator to deliver high-fidelity versions of classic handheld games. In this emulator, particular care was taken in reproducing original features such as Link Cable play (allowing for two-player multiplayer) and creating screen filters that reproduce the look and feel of the original Game Boy™, Game Boy Pocket™ and Game Boy Color™ LCD screens.
