What it means is that the cart was a different game (or was blank) and then someone "flashed" the cart to turn it into a super dodgeball cart... the game works fine(some flashes have sound problems i have heard but i have never had a problem with it) and I don't see why it would be more likely to break then a normal cart... if you want more info on it you would realy have to ask someone on the tech forum (I realy don't know anything about it)
