well this sucks, isn't it legal to have a copy of any game you have legitimately bought? i have a flashcard, but only to save having to shuffle through the multitude of games I've bought when i want to play a specific game while stuck in a car packed with other people.
oh, and the only reason I've ever had copies of games that I've never bought is when i was deeply unsure about the game so I've tried a ROM of it as a demo, then if it's a worthwhile game, I'll go out and buy it the minute i have the expendable cash to do so, and delete the fake(of course if it's no good i'll delete it too).
I don't ever want to pay $70 for an absolutely terrible game Again and find out that since I've opened it can't get my money back(a prime example being the phantom hourglass, i hate stylus-only controls with a burning passion). and since I'm not made of money this is usually a nasty "punch to the face" for me.
also, some games are NEVER released here in australia and as a last resort i have had to download them. Exhibit A being Soma Bringer, one of my all time favourite ds games. as far as I'm aware, an English version of it is non-existent, but if I found out there was an English version i would search all over for a copy and buy it.
altogether, the whole anti piracy thing doesn't bother me so much, as i'm just gonna have to be really damn careful when i pick my games(and watch what I'm doing on the inter-webs) . more the notion that I'm probably gonna have to buy yet another damn DS just to play the next new golden sun/pokemon/whatever else I wanna play. i swear i grow far less content with Nintendo each time they release another silly console full of gimmicks. oh and the whole constant wireless kinda sucks, takes the point out of it being a hand-held if you ask me, waste of battery life.
all in all, i have nothing against flash cards as long as they're used in a LEGAL manner.e.g. homebrew games, and back ups of games you have actually bought(which as far as i know is legal).
just my opinion, don't go raging at me cause you have nothing better to do than try and start fight's on the net. that being said, i have nothing against a little constructive criticism.
