There's other stuff up there that I didn't highlight but that part alone about the iDS ROM support on any DS system should prove this to be fake. The DSi just came out maybe a month or two ago? Mayber sooner? I don't know... But I seriously doubt someone's already managed to dump the original firmware, tweak it, and convert it into an emulator this soon. Plus what about the unique features the new DS has? Camera? No SLOT-2 device? Micro-SD card support? Dual touch screens? Considering most games that'll come out for it will use a dual touch screen, how would you implement that feature in previous DS systems? Either these are so-called "promises" they're making, or they're just some really retarded piraters.
