when i pick this game to play and starts loading it says:
rom loading failed
disk error=2147483632
please reset system

Backup and reformat your MicroSD, and put all the files back on.And make sure you have the latest firmware. http://www.linfoxdomain.com/ds/

I have the similar problem also with the game, I have a DSTT card with latest firmware from www.linfoxdomain.com
It still freezes in the middle of loading and replies with 'disk error =-85 please reset system'.
Can anyone help me?

as Anandjones said backup and reformat your card then put ur files back on. simple as that really. Also ive finished the game and it is AWESOME
