So I installed Home Design Story for the gold it gives you in DS. Everytime I reach a goal (Install, level 7, level 15) I don't receive the gold in New Dawn. I have to go start up my old DS and receive the gold and then it shows up in my New Dawn. Just writing this to say you may not wanna uninstall DS just yet.

BTW I never installed these games because on my goals it never told me what the reward was for downloading them. It was always blank. Little did I know how much gold it gives or I would have been playing these games all along.
