Fake Dragon Quest IX ROM punishes overeager pirates
Okay, let's get this out of the way right up front: Downloading what you think is a ROM of the Japanese release of Dragon Quest IX, days before it even comes out, is not cool. It turns out that it will probably also end up being hazardous to your DS.
DS Scene reports that a file going around, labeled "Dragon Quest IX JPN DSi Enhanced NDS iND," is actually not Dragon Quest IX at all, but rather a malicious program that can overwrite a DS's firmware and render systems unusable. The program is disguised as a hentai slideshow called "DS Owata," which is itself disguised as Dragon Quest IX.
Our advice in this case is to do your very best not to be a pirate and just buy the thing when you can. Square Enix booby-traps its legitimate games against piracy anyway.
