Hackers Beware R4 clone will brick your NDS

[L.C.E.C.]

Hackers is not the correct word...
Also, I just use M3 over R4.

Also, It's not for Piracy. You can dump/download games you already have and not carry the cartdridges around, use the M3/R4 as a second copy of a game you have. Also, you can download demos, homebrew, and play NES Games on it.
