As the title says, and perhaps as a shock to some of y'all, but the DS actually released a peripheral that allowed the second/GBA slot to be used as an optical mouse. I don't believe if any other game actually used this besides Slide Adventure MAGKID, as it's often packaged with it. I'm sure a Japan-only Nintendo game being the only example of this being used might make it a hard sell to consider emulating, seeing as the game is probably more famous for being in Smash than what the game...
Has any emulator tackled trying to emulate the optical mouse for games like Slide Adventure MAGKID?
