So my dad bought my brother a DS for Christmas and unfortunately, since I wasn't there to help him pick out a flashcart, he ended up getting a GEi. Can't really return it. Anyway, the problem being the thing has horrible compatibility with a bunch of ROMs that work on my DSTT. Earlier stuff seems to work. Pokemon Platinum works fine, as does FF3 and 4 (No complaints, as far as I know) but The World Ends With You and Kingdom Hearts doesn't seem to. I checked with the GEi site and it seems clean ROMs only work. TWEWY and KH were clean as they DO work on my DSTT. What's up then? Do I need to do a firmware update? If so, where do I get the latest firmware?
