For the old GW multi screen, it was all about having some of the first d-pads known to man and having split screen functionality. Now nintendo ommited this for the Game Boy lineup- but then….
The DS lineup came out- followed by the 3ds lineup featuring the same principal. But did the ds, ds lite and dsi. Did the GW multi screen trigger the ds? tell me in the comments! btw, if your d-pad is on the right for your ds, it’s fake.
