Do emulators work under license
Does Nintendo lose any potential sale?
Does even a relevant percentage of people play original games on the Dolphin? Like...... lets say 0.5% at least?

I'm not saying the Dolphin Emulator as a whole isn't losing Nintendo money, but the individual act of playing a Nintendo game you own or have owned on the Dolphin emulator is not wrong to me in any way.

The emulators themselves don't use any copywritten material.

I definitely bought xenoblade, Last Story, Skyward Sword, Fragile Dreams which I wouldn't have otherwise boughten because the graphics of the wii are so poor from a technical perspective. 

You also know that anyone with half a brain can pirate on wii. So it's not like because of an emulator there's necessarily that much more piracy. However, Since the PC provides a better experience on most games (some games are still bugged), and is a bit easier (don't have to burn disc) it makes more sense for the pirates to pirate on PC instead of wii.

There's nothing wrong with the emulator, just the people that steal while using it. Just like the people that use wii and pirate. There's nothing wrong with the wii. What you're saying is like saying youtube is wrong because so many people use it to view/post copywritten material. When it's the people abusing it that are at fault.

If the wii's graphics weren't so bad technically in the first place, it wouldn't be possible to emulate. And piracy would exist only on console.

I am just going to go ahead and point out here that you do not need to burn wii games onto blank dvd's anymore for playing images on the console, there are others ways of doing it, very easier ways, if you had say for example isos on any external harddrive which happened to be formatted to fat32 a disk format the wii can read from there might be a way :)

Thanks for that.

Well, I don't care for the pirates. I can use the emulator to have a better experience with the games I bought. Yes I paid money. I do nothing wrong, if I use the emulator. And I don't see an argument of you, that makes me feel wrong, if I use one. Keep in mind, I don't pirate. So why should I feel wrong for using an emulator? Even if I skip the purchase of the console and play the games on emulator, there is nothing wrong about that.

I'm also not in charge for bringing profit to Nintendo. Sony and it's offerings also cost Nintendo  sales, Nintendo could sell more and get more profit, if Sony wouldn't release a competing console. But that doesn't make it wrong for Sony to release a console. Same for emulator. If you own the old game, play it on emulator and Nintendo loses sales on Virtual Console, than is not the emulator or you wrong.

You use stolen/hacked Wii hw libraries, the creator doesnt have any right to use them, even less you
doent care what you buy or have bought, you havent bought any Wii console, you arent licensed to use the Wii hw, if you use hacked hw you are stealing Nintendo their IP
wether you feel good or bad about it is irrelevant

Dolphin doesn't use stolen/hacked Wii HW libraries. And otherwise it is the same as saying, that you can't use a car-radio (you bought) if you don't own a car.

The only thing where Nintendo could take action is if a bios was included in the emulator. That's copyright material.

"Despite three years of active development as an open source project, Rydgård told me Nintendo has never contacted the group with legal threats or demands. Dolphin actually skirts the legal issues that concern most emulators--while it's entirely legal to dump your own ROM images and system BIOS files, obtaining those files online enters shady territory."

"Unlike the UltraHLE guys (of N64 emulation fame), we've never heard from Nintendo at all. . . .The emulator itself is legal: as long as you rip games that you buy and play them with Dolphin there's nothing that's even questionable going on. Dolphin does not require the use of a BIOS file due to the 'OS' on Nintendo systems being built into each and every game."

100% legal.

And even downloading games you own (if you don't want to rip them) is legal in many countries.

Wow, I never knew the OS of the Wii is included in every game. Seems to be pretty small if you look at games like NSMBW with a size of 387MB (also meaning OS != NAND). I guess "You learn something new every day" IS true afterall^^
