OK, this is not really a game, nor an application and it is completely useless However it is quite fun and addictive Loituma Girl DS is small toy for your Nintendo DS. This gadget is an adaptation of 2 original flash animation (which can be found here and here). You can get more information regarding this popular animation on Wikipedia and at loituma.hu. All the credits goes to the original flash animations, musics and cartoons.
It doesn´t need comic book ds. I tried the sc.nds on my SuperCard Lite and it worked. You could try renaming the .ds.gba to .nds and try that on your cards instead or try launching it from moonshell.
