[Image: Hairo Satoh’s modded Game Boy can play Nintendo DS games as well as Game Boy Advance cartridges. https://platform.theverge.com/wp-content/uploads/sites/2/chorus/uploads/chorus_asset/file/25845630/gameboy_nintendoDS4.gif?quality=90&strip=all] Hairo Satoh has managed to squeeze a Nintendo DS into an original Game Boy that still closely resembles the original hardware. DS games are playable thanks to an added card slot on the bottom, a second screen that pops out the top, and a touchscreen upgrade. Now just give it an 3DS autostereo screen and stubby joystick! Correction: It was the 3DS, not the DS, that had a stubby joystick.
