Never heard of a 2sf? Well neither had we until our friends at Zophar’s Domain brought it to our attention. 2sf is an emulated sound format for Nintendo’s popular handheld–think NSF or SPC for the DS. vio2sf is a Winamp/Foobar plugin that allows you to play these files back. You can grab it from Zophar here. Though Zophar doesn’t have any 2sf archives yet, a quick google search yielded us a number of sites, so it shouldn’t be hard to find your favorite DS music. Enjoy!
