This Convenient and Sleek Device Lets You Plug Four Carts Into Your Game Boy Color

Kids today are spoiled. All of the current consoles have WiFi connections and plenty of storage to hold digital games, so nobody needs to bother with owning physical media at all, much less sorting through it. But that’s a relatively new development and until just a couple generations ago, people had to maintain physical game libraries. If you wanted to play more than one game while traveling, that meant lugging cartridges around with you. Thankfully, Solderking has a solution in the form of this convenient and sleek device that lets four cartridges plug into a single Game Boy Color.

The Game Boy Color, notably, only had a single cartridge slot. That oversight by Nintendo forced players to switch out cartridges every single time they wanted to play a different game. It was pure chaos and insanity—disorder the pampered children of today will never understand. Solderking’s device brings order to the Game Boy Color universe and only adds a little bit of heft and unwieldiness to the console. Players can plug up to four cartridges into this device. The device, in turn, plugs into the Game Boy Color’s cartridge slot.

Of course, the Game Boy Color can’t recognize four cartridges at once. It only recognizes one of the four at any given time. To switch to a different game, the user must rotate the device’s mainboard to the correct orientation and plug it back in.

To enjoy the benefits of Solderking’s ingenuity, one must fabricate three unique PCBs. The first plugs into the Game Boy Color’s cartridge slot. The second PCB connects to the first and provides an external interface for the third PCB via a female pin header. The third PCB has four cartridge slots and four sets of male header pins. The PCB’s traces connect the cartridges pins to the male pins. By rotating the third PCB, the user can choose which cartridge connects to the header pins that feed into the Game Boy Color’s cartridge slot. It’s so simple that we’re amazed Nintendo never made such a device!
