looking for japanese ds game - different pictures

does anyone know the name of a japanese nds game where it shows the same picture on both screens, and you need to circle the differences between the two pictures? i had it once and somehow lost it. i was totally addicted to that game... and i feel the pain of withdrawal. please help.

I know that game xDDDDthe japanese names is------>Unou no Tatsujin: Soukai! Machigai Museumthe english name is quickspot

you are effing wonderful.
thank you :D

I know your question has been answered but the following are also spot the difference games in Japanese:0736 - Akko ni Omakase! Brain Shock
1010 - San-X Chara Sagashi LandI've not tried them as this is not my kind of game but I thought you might like them.

extrapages, you should like "Unou no Tatsujin Soukai Machigai Museum 2" even more is supposed to be Quickspot2 but just that the English version is not out yet. It has more features than Quickspot.

do you understand japanese?
