I'll tell you in a more elaborated way. Due to legal issues on most countries I know of, by buying a single game you don't buy the right of owning all the games of the same type. That means that you own a SINGLE copy of it, even if all the other copies of it are exactly the same. You don't own a DS, and the only known way to dump a DS games successfully to a PC is using it, thus the conclusion is that you downloaded/shared from someone, which means you're using an illegal copy from the game you might/do own.I just came to the conclusion that this is quite a waste of time.
I have no Idea why you (at least it looks as if you do so) are just trying to be unfriendly to me / insulting.
You might want to consider to adopt some better manners when communicating with someone who has just giving you a compliment for good work and maybe formulated a question a little bit to unaware of legal rights.
Is it clear now?
