I can't get Zelda spirit tracks to work on my m3 and I already cracked the ROM but when I start it up all I get is the Nintendo logo and it just stays there.
You can get more info on the official topic http://forum.romulation.net/index.php?topic=28754.0, but if i'd guess i'd say you did something wrong as even the clean rom goes beyond that on most cards.
