Gotta Catch Em All! GameBoy Pokemon Trader

One of the unique features of the original Game Boy (and its immediate successors) was the ability to link two or more units together using the Link Cable. While this enabled multiplayer gaming for many games, no game used it as much as the original Pokemon games. Without a friend who owned the opposite colour game and a link cable, it was impossible to catch all 150 original Pokemon! Well, now you can trade anything you want with the Game Boy Pokemon Trader.

Of course, you could easily use this device to stack your team with custom Pokemon and completely obliterate the Elite Four (which carries a certain satisfaction if you, like me, struggled to beat them as a child), but it could also be an extremely useful tool for those researching how the Pokemon code works, how Link Cable transactions work, and content creators setting up custom scenarios (Soft Lock Picking, anyone?).

The interface is very easy to use – once powered up, connect to the WiFi network and browse to the IP printed on the custom PCB. Pick the traits you want for your traded Pokemon, connect it to your Game Boy with a Link Cable, and then visit a Pokemon Centre and enter the trading room. It’s just like trading with any other Game Boy, except you’re in total control of the entire process.
