I had my DS on me today when I went into my local game store. I had my R4 in it with a copy of the DS Download Rom (the one that the ds download hotspot DSs run). I turned on my DS and ran the rom. I walked over to the Demo DS and began to download and run the Zelda DS Trailer from my DS. The guy looked at me and he knew something was going on, but had no proof so he just dismissed it. I mean, whats to stop some clever person making a ROM that will send porn or something to the demo ds or maybe that DS bricker code and potentially causing some damage?
