I downloaded tetris for my android smartphone and i really like it but i wanted to have it on my ds. I downloaded the rom( i don't know if i am allowed to post where i downloaded it from) i put it in the sd card as always and then when i tried to find it it wasn't anywhere. I searched all the folders and nothing. When i searched for it on the computer i found it. I don't know what i did wrong, i tried to paste it like 10 times and i redownloaded it from a different website but nothing. My flashcard is Supercard DSTWO and i use it with a DSi XL. Thanks in advance.
