Well you are the only one missing out. This doesn't affect anyone but you. You wont buy the system and you wont use the emulator. That's not really anything Nintendo can do about.
That's fine. I completely accept that it's not a completely rational reason for one's desire of a product to be lowered. When we get into the areas of pleasure and motivation, rationality is often cast aside. Again, this isn't about me (though once upon a time I bought Animal Crossing for the NES games, so I am a potential customer lost). I'm explaining a reason why emulators and pirating would hurt sales even among those that don't use them.
Emulation being so imperfect by nature means that many of these games really aren't 'available' for free. Even on something like Dolphin, one of the best and most reliable emulators out there, many Gamecube and Wii games have simply never worked. Factor 5 games are notorious for not working on any emulator. So if you want to play the Rogue Squadron games, the only way is with a legal hard copy on real hardware. And even if you get a game that works in theory, it would often have glitches, unresponsive controls, a terrible framerate miles worse than the game has on real hardware, and other technical problems that make it like getting your teeth pulled.
