I stumbled upon this video yesterday while waiting for weeks for USPS to not suck and finally deliver my Pokemon Leaf Green. While I realize that this is a game developer's website, and a lot of you are probably aware of this jargon, I still find it necessary to spread the love to those who don't have it.
The link to the emulator is in the video description. No computers are required. This app is also compatable with iPod Touch and iPad. I'm unsure about Android systems, but they have a ton anyway.
[spoiler]I don't naturally condone pirating, but in cases such as these, where pirating doesn't take revenue from the developer, I find it more morally acceptable[/spoiler]
[spoiler]Since this is borderline #gaming, but also app and phone related, I posted this in the forum with the people I actually like.[/spoiler]
