GameSetWatch points to a freaky, weird homebrew DS created by developers Alpha Dream. The story goes that the team behind Mario & Luigi: Partners in Time needed something DS-like to work with before the DS was available. So the crew decided to make their own DS by slapping together a SNES controller with two Game Boy Advances. They forgot the PDA and waffle iron, cuz the DS is hot baby, hot!
