Full Gameboy Color Emulator in Javascript

It's also worth checking out Imran Nazar's excellent writeup on creating a Gameboy emulator in javascript: http://imrannazar.com/GameBoy-Emulation-in-JavaScript

This has been posted here a dozen times before, many times by the author himself.

Impressive as the emulator is, it's been suggested to him before (and he has acknowledged) that he shouldn't be running non-public-domain ROMs on his site. If he gets a C&D/DMCA takedown, I have zero sympathy.

I don't get it. What's with all the reimplementations of stuff in Javascript (and WebGL for that matter)? I understand that the Web is the next big platform, and the Javascript is currently the lingua franca of the Web. But it doesn't make any sense that vast collections of working code that happens not to be written in Javascript should be reimplemented to fit this straightjacket.

It makes far more sense for the community to focus on the development of translators -- compilers -- from other languages to Javascript, and on the optimization of Javascript engines to run such translated code. I know such systems exist (most notably for Java and C), so I'm confused by the disproportionate amount of press stories like this one get.

Of course I'm ignoring the fact that one may wish to rewrite code in Javascript because they find the language interesting. I can't say I'm one of those people.

(Note: I don't mean this to knock the author's work. Writing emulators is interesting and fun, and I'm sure he did a good job of it. But a Game Boy emulator in Javascript (the language) is no more interesting than a Game Boy emulator in PHP. The interesting part is that it is a Game Boy emulator in Javascript (the platform), which IMO should not necessitate a reimplementation of a Game Boy emulator in Javascript (the language).)

If SOPA passes, this demo will die a quick death... :-(

It won't take SOPA to kill this. The existing laws are enough.

Basically, emulators are legal (Sony v. Connectix). Pirate ROMs are not (the "24 hours" excuse is BS). Hopefully they don't provide, link to, or otherwise encourage the use of those. There are perfectly good public domain ROMs they can use for the demo.

IANAL, though, so if the person who made this gets any nastygrams, they should talk to someone who is.
