Nintendo Ninjas

Nintendo Ninjas are people who drove around suburban area looking for people using illegal ROMs of their games.

Niggas in black suits who drive large black Suburbans hired by Nintendo to investigate leaks and those who spread leaks.

Employees in black suits who drive large black Suburbans hired by Nintendo to investigate game leaks, leakers, hackers, illegal game rom sites, and those who download those roms.

They still haven't come for me, so I'm gonna give them the wakeup call by flexing my ROMS. I have 450 games on my hacked Wii, including leaked prototypes and demo discs. The entire setup costed $180. I have a DSi with TWiLight Menu ++, and a bunch of DS ROMS, and for the icing on the cake, both have NES, SNES, Genesis/MD, SMS, etc. ROMS and they run perfectly. All of that and Nintendo still hasn't come for me. Come holla at me.
