sorry for late reply But its in his discord you can go into it by going into the Garrys mod 3ds thread then pressing discord try all 3 of them to (at the moment it only works with New3DS)
hey dude i dont think people will make a port of it but you can get SonicCD but it will be slow like about 28 fps or wait until the sonicmania for Old2ds or Old3ds comes out (You Will Need a Data.rsdk for both)
