So I've been trying every known resource from Console Tool all the way to Tinke and everything in between but I am unable to gain access to all of the character sprites in the game. I know where they are located but anything beyond that might as well be me trying to translate a foreign language...
@Xdqwerty, You do realise that just about any SD card formatted to FAT32 should work with the DSi. I think, 16GB or 32 is about enough to load all of your games.
