You won't have the legal right to ever pirate their games, but if joe on eBay over there selling ttyd at 100 bucks, and if you can't get it otherwise officially by Nintendo, then I'd say pirate away for their older, inaccessible, games.

Besides, your IP service won't give 2 darn's and a half if you pirate their older inaccessible games.
Piracy isn't always just a black & white area and has a lot of cases where it falls into the gray or even ethical area depending on, again, on each individual case.
