Sorry for butting in, but please give people a break, not everyone who signs in here knows that Dolphin is a demo (labeling it "teaser" doesn't tell exactly what it is, a lot of emulators have weird names). And he/she didn't say get it PERFECT, they just want it to open. Also many emulators for other systems can run games that were released after the emulator was finished.
Now for defense of a LOT of people (this is why I decided to speak up):
Just because someone asks for help getting a game to work on emulator, DOESN'T mean that they don't own the game/console. Many people simply PREFER playing on the computer, especially if they own laptops. My all time favorite console is the computer, so when ever I buy a game for GBA, N64, etc.. I ALSO put it on computer.
Sorry if I'm piping up in a subject I have no right to, but I find "Just go buy a real one" as annoying as when you're getting into an argument over a Movie or Book universe (example: Lord of the Rings, Star wars) and someone spouts "well, you know it never REALLY happend, so it doesn't matter". grrrrr
Again sorry if I'm spouting gunk here,
I try never to flame,
The Saxman
