I don't have anything for the DS to play non-regulation games, but I don't want people to get bricked either.
|The "leaked" version of Dragon Quest IX is malware. The ROM was dumped early on to Japanese bulletin board 2chan and is actually a hentai slideshow show called "DS Owata".
Maybe download "Dragon Quest IX JPN DSi Enchanced NDS iND" if you'd like a hentai slideshow? Oh, this bricks your DS. Buying it legally does not.
