i Have had some problems downloading also. Almost (i think) 5 of the 37 nds Roms i've downloaded were corrupt. (Starwars clone wars ect)

neezer they were most likely not corrupt....they probably have compatibility issues with your cards firmware......using an r4 right? i know that because you mentioned clone wars rom and that one has had some sort of issues with most r4 cards the rest of your non-working roms you most likely will have to replace the arm7 file look around in support these problems are not caused by anything romulation did or did not do

If you extracted them right, they weren't corrupt. All to do with your flashcart. Games are?
