Ripping Tool recommendations?

[Garamonde]

Dark Dawn is a DS game, so I would personally try all of them since it's trial and error. I would try Oil of Vitriol first. To use this, you have to first unpack the .NDS ROM using DSLazy, then open the folder titled "NDS_UNPACK", and check to see if there are .NCLR, .NCER and .NANR files. Only then will OoV work with it. If the game doesn't use those files for the graphics, then next you will have to try either ConsoleTool or Tahaxan (I'd use Tahaxan but it's near-impossible to find an archive that has all the necessary files... RomHacking.net doesn't have all of it, so try ConsoleTool). These programs let you view the game data and even decompress certain file types. They only export single sprites (as far as I know, don't quote me on that as I haven't really used them myself), but it's a very useful tool for extracting graphics. If you want more help with that, there is a member here by the name of "redblueyellow" who is a wiz at that stuff (he has a thread in the main "Submissions" forum). I'd ask him to help you with this.
