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.

A squadron of highly trained individuals hired by Nintendo to take down romhacks, copyrighted and leaked content very quickly.
They're never seen, only heard of.

For a second, you were playing a romhack, you blinked your eyes and now it's gone.
Fatalities including, but not limited to:

AM2R,

Pokémon Uranium,
SMBX,

PM,

every single one of Souljaboy's "consoles",

etc.
Person 1: Aww dude, I was gonna download this awesome romhack, but now it's gone.
Person 2: Oh, it seems the Nintendo Ninjas have done their work swiftly.
