Well it does work on sc sd but has save problems, first off you need to patch it to save to a nds card, anything with a 64k save will do i used mario 64. Then when you get to the file select screen yourll have to delete the top save, theres 2 buttons on the right of the file select screen, click the bottom one then touch file 1 and delete it, now start a game on the fresh file and it will work, the only problem is when you reboot the ds the save will become corrupt   so its playable but if you wanna see the whole game yourll have to keep the ds on ;-)
