Once hacked, the Zune HD's rabid fanbase wasted no time in ensuring the device could play Doom. Now, the ZuneBoards want to give it Zelda, too. User BackAtIt has taken the wrappings off the first working emulator for Zune, which is currently capable of playing Game Boy and Game Boy Color ROMs, but little else -- though this "Visual Boy Zune" app is ported from the same VisualBoyAdvance code that's enabled handheld emulation since 2004, it's in early alpha with quite a bit of work left to do. A recent update enabled state save emulation and a ROM selector, but there's no audio output, let alone Game Boy Advance support; BackAtIt says he'll need to rewrite much of the codebase to take advantage of the Zune HD's Tegra architecture. Still, it's never too early for a proof of concept video, and you'll find two blurry ones after the break -- unless you'd rather try it out for yourself at the source link.
